Abstract

The syntheses, spectroscopic data and crystal structures of (H2NCOCH2CH2-C)(R2NCS2-S,S/)3Sn (1), (H2NCOCH2CH2-C,O)2SnCl2 (triclinic polymorph) (2), (H2NCOCH2CH2-C,O)(2-H2NCOC6H4S-O,S)SnCl2 (3) and Sn(C11H9N2O2)Cl3 (4) are reported. The tin atom in compound 1 (R = Et) is coordinated by three chelating dithiocarbamate anions and a C-bound non-chelating amidoethyl ligand to generate a SnS6C pentagonal-bipyramidal coordination polyhedron. Compound 2, which features SnC2O2Cl2 octahedra, was crystallised from mixed solvents (ethanol and water) and complements the two known monoclinic forms. Compound 3 arose unexpectedly due to ligand disproportionation of the tin starting material and a “trans-esterification” reaction of the starting ligand: distorted SnCSO2Cl2 octahedra are seen in the crystal structure. Compound 4 arose from another ligand disproportionation reaction and features neutral complex molecules with N2OCl3 donor sets coordinating to the octahedral tin atoms.
