This Day in Science History - March 20 - Mayer and Conservation of EnergyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
March 20th marks the passing of Julius Robert von Mayer. Mayer was a German physician who had a hobby of studying physics. Most of his work centered around how energy was transferred from one form to another. He was one of the first to recognize that plants converted light into chemical energy, and the process of oxidation was the primary source of energy in living creatures. He also outlined the earliest versions of what would become the first law of thermodynamics by writing "Energy is neither created nor destroyed". He attempted to publish his ideas as conservation of force, but had several basic errors due to his lack ...

Savannah's Nuclear BombEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
About.com is holding a meeting in Savannah this weekend so I suspect my coworkers would be interested to know that there is a live nuclear bomb off the Georgia coast. In February 1958 a B-47 bomber on a training mission out of Homestead Air Force Base in Florida had a collision with an F-86. The pilot of the F-86 parachuted to safety and the fighter jet crashed. The B-47 also sustained damage. The crew requested and received permission to jettison the 7,600 pound Mark 15 bomb it was carrying so that the aircraft could more safely land at Hunter Air Force Base. The bomb was lost somewhere in Wassaw Sound off the shores of T...

Ethyl (2E)-2-(hydroxyimino)propanoateEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The molecule of the title compound, C5H9NO3, is essentially planar [the maximum deviation for a non-H atom from the mean plane is 0.021 (3) Å] due to the π-conjugation of the hydroxyimino and carbonyl groups, which are trans to each other; ab initio calculations in vacuo at the DFT (B3LYP/6–311G**++) level of theory confirmed that E conformer is indeed the lowest in energy. The packing in crystal structure is influenced by strong intermolecular O—H...N hydrogen-bonding interactions between oxime groups and also by π-stacking of the molecules due to the carbonyl and oxime group orbital overlap [interplanar distan...

The title complex, [Cd2(C8H7O3)4(C20H22N4O)2], forms a dimer of the paddle-wheel type, located on a crystallographic inversion centre. The CdII ion is hexacoordinated by four carboxylate O atoms [Cd...O = 2.280 (2)–2.404 (2) Å] from two chelating 4-methoxybenzoate anions, and two N atoms [Cd...N = 2.313 (2) and 2.332 (2) Å] from one chelating 2,2′-dimethyl-3,3′-(oxydiethylene)bis(1H-benzimidazole) ligand. In the crystal, molecules are linked by a weak intermolecular C—H...O hydrogen bond and an intermolecular C—H...π interaction. (Source: Acta Crystallographica Section E)

The Au atom in the title compound, [Au(C10H12NOS)(C18H33P)], is coordinated within an S,P-donor set that defines a slightly distorted linear geometry [S—Au—P = 174.54 (2)°], with the distortion due in part to a close intramolecular Au...O contact [3.1702 (16) Å].

(meso-5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene)copper(II) bis[O,O′-bis(4-methylphenyl) dithiophosphate]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The title compound, [Cu(C16H32N4)](C14H14O2PS2)2 or [Cu(trans[14]dien)][S2P(OC6H4Me-4)2]2, where trans[14]dien is meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene, was obtained by the reaction of [Cu(trans[14]dien)](ClO4)2 and [(C2H5)2NH]2 [S2P(OC6H4Me-4)2]2. The CuII atom lies on a centre of inversion and possesses a relatively undistorted square-planar coordination arrangement with four N atoms of the macrocyclic tetramine trans[14]dien [Cu—N = 1.9716 (19) and 2.0075 (19) Å]. The two uncoordinated [(4-MeC6H4O)2PS2]− groups act as counter-ions to balance the charge and interact with the...

catena-Poly[sodium-di-μ-aqua-sodium-bis[μ-2,2,2-trichloro-N-(dimorpholinophosphoryl)acetamide]]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The title compound, [Na2(C10H16Cl3N3O4P)2(H2O)2]n, can be considered as a two-dimensional coordination polymer in which one-dimensional chains are connected to each other by intermolecular C—H...O hydrogen bonds involving the water molecules. The NaI ion is five-coordinated in a distorted trigonal-bipyramidal geometry. The connection between the two NaI ions is facilitated by the two μ-O atoms of the carbonyl group of the 2,2,2-trichloro-N-(dimorpholinophosphoryl)acetamide (CAPh) ligand. A bridging coordination of the CAPh ligand via the carbonyl O atom is observed for the first time. The bridging water molecules form i...

Diacridinium hexachloridoplatinate(IV) dihydrateEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The asymmetric unit of the title compound, (C13H10N)2[PtCl6]·2H2O, contains a protonated acridine cation, one half of a [PtCl6]2− dianionic complex and a solvent water molecule. The octahedral [PtCl6]2− dianion is located on an inversion centre. π–π interactions between neighboring acridinium cations produce stacks along the a axis; the shortest distance between the centroids of the six-membered rings within the cations is 3.553 (9) Å. In the crystal, two independent intermolecular O—H...Cl hydrogen bonds, both involving the same Cl atom of the anion as acceptor, give rise to chains also running along the a...

Substitutional disorder in the ionic diorganoantimony halide adduct [bromido/chlorido(0.33/0.67)][2-(dimethylaminomethyl)phenyl][2-(dimethylammoniomethyl)phenyl]antimony(III) 0.75-bromide 0.25-chlorideEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The title complex, [SbBr0.33Cl0.67(C9H13N)(C9H12N)]Br0.75Cl0.25, exhibits substitutional disorder of both halogen atoms in the asymmetric unit, however, with different occupancies. Thus, the halogen atom bonded to Sb has 0.67 (4) occupancy for Cl and 0.33 (4) for Br, while the anionic halogen atom shows 0.75 (4) occupancy for Br and 0.25 (4) for Cl. An N—H...Cl/Br hydrogen bond is established between the cation and the halide anion. The coordination geometry of the Sb center in the cation is distorted pseudo-trigonal-bipyramidal as a result of the strong intramolecular N→Sb coordination trans to the Sb—Cl/Br ...

In the title compound, [Mg(H2O)6](C16H16NO5S)2, the Mg2+ ion (site symmetry 2) adopts an almost regular octahedral coordination geometry.

A new crystal modification of diammonium hydrogen phosphate, (NH4)2(HPO4)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The addition of hexafluoridophosphate salts (ammonium, silver, thallium or potassium) is usually used to precipitate complex cations from aqueous solutions. It has long been known that PF6− is sensitive towards hydrolysis under acidic conditions [Gebala & Jones (1969). J. Inorg. Nucl. Chem. 31, 771–776; Plakhotnyk et al. (2005). J. Fluorine Chem. 126, 27–31]. During the course of our investigation into coinage metal complexes of diphosphine ligands, we used ammonium hexafluoridophosphate in order to crystallize [Ag(diphosphine)2]PF6 complexes. From these solutions we always obtained needle-like crystals which turned ...
