Both the fac-and mer-isomer of 'PrSnCI 3 • 2DMSO were isolated under slightly different reaction conditions. The conformations of these octahedral complexes with a c/s-arrangement of the two solvent molecules were confirmed by single crystal X-ray diffraction experiments. In both cases, the asymmetric unit contains two molecules. While the fac-isomer crystallizes in the centrosymmetric space group P2 1 /n with a = 14.638 (3) A, b = 15.073(3) A, c = 15.916(3) Α, β = 110.86°, the merisomer crystallizes in the acentric space group P2^ with a = 7.150(2) A, b = 15.155(3) A, c = 14.738(3) Α, β = 93.43(3)°. In both isomers the bonds trans to the isopropyl groups are shortened.

“…As the PQS value for the amide oxygen is not directly available in the literature, for calculations of the QS values the PQS of {O=C(Me)-N} tba was taken from that of N,N-dimethylacetamide (dma), in view of the fact that N,N-dialkylamides coordinate to organotin(IV) cations through their carboxylamide oxygens. 15 The values for monodentate carboxylate groups were obtained from data published by BARBIERI et al 14 314 …”

Effects of side-chains ofN-acetylamino acids on the structures of their triphenyltin(IV) complexes

Triphenyltin(IV) complexes of N-acetylglycine, N-acetyI-L-leucine, N-acetyl-L-asparagine and N-acetyI-L-tyrosine were prepared by two methods and characterized by means of different spectroscopic methods (FTIR, multinuclear, IH, 13C and Hgsn NMR and lWSn M0ssbauer). The spectroscopic data indicated that the N-acetylglycine complex adopts a trigonal-bipyramidal structure in which the monodentate carboxylate and the amide -C=O group are bound to the same organotin(IV) moiety. The other three complexes are linear oligomers in which the planar Ph3Sn(IV ) is coordinated axially by a monodentate carboxylate and an amide -C=O from two different ligands. At the C-terminal end of the oligomer chain there is a tetracoordinated tin(IV) with a monodentate carboxylate as donor group.

“…The axial bonds will have greater p character on Sn and little s character, thereby increasing the Sn-O distance. The Sn-C1 bond shows no significant difference from the Sn-CI distances in the octahedral complexes [2.474 (2) to 2.524 (4)A] (Aslanov et al, 1978: Pelizzi & Pelizzi, 1975, which are both cis-dichloro species with likely C1...C1 interactions. The S-O bond length is indicative of multiple-bond character and the stereochemistry around the S atom is consistent with the presence of a lone-pair of electrons on this atom.…”

The structure was refined to an R of 0.037 for 1685 unique diffractometer data. The molecule lies on a crystallographic centre of symmetry situated at the centre of the C(4)-C(4') double bond of the bidentate disulphoxide ligand. This group is bonded to two symmetry-related Sn atoms to form a bridged species. The unique Sn atom exhibits a trigonal-bipyramidal coordination geometry, and is bonded to three phenyl groups in the equatorial plane and to a CI and an O atom in the axial positions. The n-propyl substituent coordinated to the S atom is disordered. to 0.919 for the full data set. Equivalent reflections were averaged to give 1685 unique observed intensities IF > 3a(F)l. Cell dimensions were derived from the angular measurements of 15 strong reflections (45 < 20 < 550).The Sn-atom position was determined from a Patterson synthesis, and the remaining non-hydrogen
