    No full text
    The title compound, [Sn(CH3)2Cl2(CH4N2S)2], crystallizes with two half-molecules in the asymmetric unit. Both molecules are completed by inversion symmetry with the two SnIV atoms located on inversion centers. The metal atoms have distorted octahedral coordination environments defined by two Cl atoms, two C atoms of methyl groups and two thiourea S atoms. In the crystal, molecules are linked via N—H...Cl and N—H...S hydrogen bonds, forming a three-dimensional structure

    Five new molybdato (four) and hydrogenomolybdato (one) adducts and complexes have been synthesized and studied by infrared spectroscopy. The suggested structures are all discrete, the molybdate anion behaving as a trichelating, a monochelating, a bridging, a tetrachelating and a bichelating ligand. The environment around Zn, Co, Cd is tetrahedral or trigonal bipyramidal also for Zn - while being octahedral for Sb. The Cd pentanuclear adduct has a two metallic components structure, a tetranuclear anionic one with a tetrachelating molybdate, the second being a neutral dehydrated adduct component. The suggested structure for the hydrogenomolybdato adduct is discrete, the hydrogenomolybdate being present as a hydrogen bonded dimer behaves as a bridging bidentate ligand. The water molecules can be considered as a coordinating ligand or lattice. When secondary interactions through hydrogen bonds involving the water molecules are considered supramolecular architectures are obtained

    In the title compound, (C12H24N)[Sn(CH3)3(C6H6O3P)2], the SnMe3 residues are axially coordinated by two monodentate [PhPO3H]− anions, leading to a trigonal–bipyramidal geometry for the SnIV atom. The two [SnMe3(PhPO3H)2]− anions in the unit cell are associated into infinite chains along the a axis by O—H⋯O hydrogen bonds involving the hy­droxy group of the hydrogen phenyl­phospho­nate ion. The chains inter­act with one another via O—H⋯O hydrogen bonds along the c axis. These networks of anions assemble with the dicyclo­hexyl­ammonium ion through N—H⋯O hydrogen bonds, forming a three-dimensional network
