The properties of vinyltin and phenyltin complexes [Sn(CH=CH₂)₃{μ-OOCC₆H₃(NH₂)₂-3,4}]_n (1), [Sn(C₆H₅)₃{OOCC₆H₃(NH₂)₂-3,4}] (2), [Sn(C₆H₅)₃{OOC-2-C₆H₄N=NC₆H₄N(CH₃)₂-4}] (3) and [Sn(CH=CH₂)₃{OOC-2-C₆H₄N=NC₆H₄N(CH₃)₂-4}] (4) have been investigated. The structures of complexes 1, 2, and 3, have been determined by X-ray crystallography. Compound 1 is a distorted trigonal-bipyramidal complex and compounds 2 and 3 adopt a distorted tetrahedral structure. Complex 1 is a single-strand polymer with a bridging 3,4-diaminobenzoato ligand coordinating via the O(1) atom of the carboxylato group and the nitrogen atom of the para-amino group. The oxygen and nitrogen atoms occupy the axial coordination sites. The Sn(1)−N(2A) bond is weak. In complexes 2 and 3 the carboxylato ligands are strongly coordinated to the central atom via one oxygen atom, and the Sn(1)−O(2) distances are considerably longer. Weak interactions of the central atom with the amino group in complex 1, and with the O(2) atoms in complexes 2 and 3, as well as the hydrogen bonds, stabilize the crystal structure. The complexes are effective cytostatic agents.
