X-RAY CRYSTAL-STRUCTURE ELUCIDATION OF TIN LIGANDS OF HETEROBIMETALLIC COMPLEXES

The structures of two tin compounds, containing thiolate ligands, were determined by X-ray diffraction, (Ph)(3)Sn(SPh), 1, and (Ph)(2)Sn(SPh)(2), 2. Compound 1 belongs to P2(1)/c space group with cell parameters a=7.745(2)Angstrom, b=16.411(3)Angstrom, c=16.120(3)Angstrom, beta=93.56(3)degrees and Z=4, Compound 2 belongs to P $($) over bar$$ 1 space group with cell parameters a=9.449(2)Angstrom, b=10.310(2)Angstrom, c=12.430(2)Angstrom, alpha= 95.390(1)degrees, beta=103.190(1)Angstrom, gamma=107.440(1) and Z=2, The introduction of two PhS(-) ligands around the tin atom did alter the expected tetrahedral geometry for compound 2, Some of the determined angles were <C21SnC31, 119.3(2)degrees; <S1SnC31, 102.4(6)degrees; <C21SnS12, 105.7(1)degrees.
