AbstractTri-n-butyltin diphenylphosphinate (n-Bu)3SnO2PPh2 has been synthesized by the reaction of (n-Bu3Sn)2O with Ph2POCl in toluene. An X-ray diffraction study of (n-Bu3)SnO2PPh2 shows that the structure is polymeric and consists of helical chains in which (n-Bu)3Sn groups are linked by O-P-O bridges. The geometry about tin is trigonal bipyramidal, with n-butyl groups in equatorial positions and an axial O-Sn-O angle of 176.2 (2)°. IR and Raman spectra of (n-Bu)3SnO2PPh2 are given and assigned. The mass spectrum is reported and discussed.

Abstract The organocyclotriarsane, CH3C(CH2As)3 (1), reacts with chromium hexacarbonyl on ultraviolet irradiation to give the complex CH3C(CH2As)3Cr(CO)5 (2), in which the cyclo-triarsane is behaving as a monodentate ligand. The crystal structure of 2 has been determinated by X-ray diffraction. The monoclinic unit cell (space group P21/n) contains 4 isolated molecules in a hexagonal closest packing. The mass spectrum of 2 shows the parent peak and clear fragmentation patterns. The infrared and Raman spectra are reported for 1 and 2 in the 3000-30 cm-1 region. Most of the fundamental vibrations are assigned.

A Cu(II) complex of the amino acid L-selenomethionine of stoichiometry Cu(L-SeMet)2, has been prepared and characterized. Crystallographic data were obtained by means of X-ray powder diffractometry and showed that the compound is isostructural with the related complex of L-methionine, Cu(L-Met)2. The structural analogy is also supported by the analysis of the IR and Raman spectra of the complex, which are briefly discussed in comparison with those of free L-selenomethionine.

The crystal structure of [P(C6H5 )4][B6H6(CH2Si(CH3)3)] has been determined by single crystal X-ray diffraction analysis; monoclinic, space group P21/n with a = 16.140(2), b = 11.646(8), c = 16.731(3) Å, β 109.664(11)°. The 11B NMR spectrum reveals features of a mono hetero substituted octahedral B6 cage. The 13C NMR spectrum exhibits a quartet at +0.18 ppm with 1J(C,H) = 118 Hz for the three methyl groups and a weak multiplet at -0.65 ppm for the methylene bridge due to quadrupole coupling with the boron atoms. In the 29Si NMR spectrum a decet at +2.25 ppm with 2J(C,H ) = 6.9 Hz is observed. The B -C stretching vibration is observed at 1155 cm-1 in the IR and Raman spectrum.
