The title compounds have been prepared by reacting the corresponding diorganotin(IV) oxide with salicylaldehyde thiosemicarbazone (H 2L). [SnMe 2(L)] crystallizes in the monoclinic space group P2 1/ n with a=9.480(3), b=13.532(7), c=10.541(3) Å, β=100.33(2)° and Z=4 ( R=0.0230, R′=0.0258). [SnPh 2(L)] crystallizes in the space group P2 1/ a with a=13.483(8), b=10.078(1), c=15.622(4) Å, β=113.66(4)° and Z=4 ( R=0.030, R′=0.031). Both complexes consist of molecules in which the bisdeprotonated ligand is O,N,S-bonded and the tin atom exhibits distorted pentacoordination, with small differences between the methyl and phenyl derivatives in bond distances, bond angles and intermolecular hydrogen bonds. The spectral properties of the complexes (IR, Mössbauer and 1H, 13C and 119Sn NMR spectra) are discussed in the light of this structural information.
