Homoleptic low-valent polyazides of group 14 elements

First examples of coordinatively unsaturated, homoleptic azido complexes of low-valent group 14 elements are reported. A simple strategy uses low-valent precursors, ionic azide transfer reagents and bulky cations to obtain salt-like compounds containing E(N3)3- of Ge(ii)/Sn(ii) which are fully characterised, including XRD. Remarkably, these compounds are kinetically stable at r.t. and isolable in sub-gram quantities. This journal is

Catalytic Reaction of Methanol with a Series of Ruthenium(II) Complexes and the Mechanism of the Formation of Acetic Acid from Methanol Alone

The catalytic abilities of a series of ruthenium(II) complexes containing zero, one and two SnCl3(1-) ligands, 4> 1, 4> 2 and 3> 3, have been compared in the reaction of methanol to form acetic acid (and/or methyl acetate due to esterification), as well as their reactions with the possible intermediates (formaldehyde, methyl formate) in the overall reaction.It was found that the formation of acetic acid from methanol occured only with 3, which also converted paraformaldehyde or methyl formate into acetic acid.Complex 1 showed only a catalytic activity for the Tischenko-type dimerization (2 HCHO -> HCO2Me), and 2 exhibited an intermediate character, being able to catalyse the two reactions (2 HCHO -> HCO2Me, HCO2Me -> MeCO2H) but unable to react with methanol.Based on kinetic results for the reaction of methanol with 3, a possible reaction pathway is proposed where methyl formate and acetic acid are formed from formaldehyde competitively sharing a common reaction path.For the isomerization of methyl formate as a substrate a separate reaction path is suggested, where the Ru(II)-Sn(II) bimetallic centre of 2 and 3 converts the co-ordinated HCO2Me into a five-membered acetate bridge.

The Crystal Structures of PPh4 and PPh4

PPh4 and PPh4 were prepared by reaction of PPh4X with SnX2 in CH2X2 solutions (X = Cl, Br).The vibrational spectra of the (-) ions show three SnX3 stretching frequencies, which is caused by deviations from the ideal C3v symmetry.In the crystal structure determinations these deviations show up by slightly different Sn-X bond lengths which are explained by differing hydrogen bridges to phenyl-H atoms.The isotypic crystal structures of both compounds were determined and refined from X-ray diffraction data (R values: 0.042 and 0.034).Although triclinic (space group P), the structures are closely related to the tetragonal AsPh4 structure type.Very pure SnBr2 is prepared by the reaction of PPh4 with AlBr3 in CH2Br2 solution. - Key words: Preparation, Tetraphenylphosphonium Trihalo Stannates, Vibrational Spectra, Crystal Sructures

Vibrational frequencies and intramolecular forces in anionic tin-halogen complexes and related species

Far-infrared and Raman spectra are reported for solids containing the SnX62- (X = Cl, Br, I) and SnX3- (X = F, Cl, Br, I) ions in combination with large monopositive cations. These results include the first complete report of infrared- and Raman-active fundamentals for SnF3-, SnI3-, and SnI62-. Normal-coordinate vibrational analysis was performed for these complexes and for SnX4 (X = Cl, Br, I) under a uniform set of approximations. For a series of compounds containing the same halide it is found that the primary stretching force constants are approximately proportional to the metal oxidation state divided by the coordination number. Theoretical values for the force constants were calculated using an ionic model. These reproduce the reduction in force constant which is observed upon going from SnX4 to SnX62-.
