The organotin(IV) chlorides RnSnCl4-n (n=2, R=nBu or Ph; and n=3, R=Ph) react with 2-amino-1-cyclopentene-1-carbodithioic acid (ACDA) to give [Ph2SnCl(ACDA)] (1), [Ph2Sn(ACDA)2] (2), [Ph3Sn(ACDA)] (3) and [Bu2Sn(ACDA)2] (4). The new complexes have been characterized by elemental analysis, UV-Vis, IR,1H NMR, 119Sn NMR spectroscopy and mass spectrometry. On the basis of 119Sn NMR data the effective coordination number in solution is five. The structures of 1, 3 and 4 have been confirmed by X-ray crystallography. Crystals of 1 are monoclinic with space group P21/n. The tin environment is distorted trigonal bipyramid with Cl and sulfur atoms in apical positions. Crystals of 3 are orthorombic, P212121, and the structure is distorted trigonal bipyramid with one sulfur and phenyl in the axial position. Complex 4 crystallizes in the triclinic space group, P1?, and the Sn atom shows extremely irregular octahedral coordination with four S atoms laying in the equatorial plane. In all complexes ACDA coordinates as an anisobidentate ligand and its orientation lends to form a NH···S intramolecular hydrogen bond. The packing is also stabilized by intermolecular hydrogen bonding.
