HOMO AND HETEROPOLYNUCLEAR NEW OXALATOORGANOTIN (IV) ADDUCTS. AN INFRARED AND MÖSSBAUER STUDY

Six new oxalato homo (Sn only) and hetero (Sn, Cd, Sb) polynuclear adducts have been obtained on allowing (Me4N)2(C2O4)∙2H2O to react with SnPh2Cl2 or (Me4N)2(C2O4)SnPh2∙H2O to react with SnPh2Cl2, SnMe2Cl2, CdCl2, CdBr2∙4H2O or SbCl3 in specific ratio. The obtained adducts have been studied by elemental analyses and infrared spectroscopy and structures suggested on the basis of the spectroscopic data

NITRATO ADDUCTS AND DERIVATIVES: SYNTHESIS AND INFRARED STUDY

Five new nitrato adducts and derivatives have been synthesized and studied by infrared spectroscopy. The suggested structures are discrete or of infinite chain type, the nitrate behaving as a bidentate or a monodentate ligand, the environment around the tin (IV) centres being octahedral or trigonal bipyramidal. When extra hydrogen bonds are considered supramolecular architectures may be obtained

(Cy2NH2O2CPh)3(SnCl4)2 AND (SnBu2)4(O2CPh)16Cl6(OH)2(Cy2NH2)16: SYNTHESIS AND SPECTROSCOPIC CHARACTERIZATION

The two title compounds have been synthesized, their IR and Mössbauer studies carried out. The structures are discrete and contain mono- and bidentate PhCO2-, the environment around the tin (IV) centre being octahedral (in SnCl4 adduct), trapezoidal bipyramidal (in the SnBu2 residue containing derivative). A tetranuclear monomeric or an oligomeric structure is suggested in the tetranuclear SnBu2 residue containing derivative

Bis(trimethyl­ammonium) tetra­chlorido­diphenyl­stannate(IV)

The title compound, [(CH3)3NH]2[Sn(C6H5)2Cl4], consists of [(CH3)3NH]+ cations and [SnPh2Cl4]2− anions in which the Sn atom, located on a centre of inversion, is bonded to four Cl atoms and two phenyl rings, giving an octa­hedral geometry with the phenyl rings in trans positions. In the crystal, the cations and the anions are connected by N—H⋯Cl hydrogen bonds and C—H⋯Cl inter­actions

INTERACTIONS BETWEEN C6H4(CH2NH3)2[PhCO2]2, Et2NH2[Ph(OH)CO2] AND CuCl2, ErCl3 or SnPh3OH: AN INFRARED STUDY

The interactions of benzoic or salycilic acids salts with di-, trihalides or SnPh3OH have yielded four new complexes and adducts studied by infrared.The suggested structures are discrete or of infinite chain type, the anion behaving as monodentate and hydrogen bonding involved, or bidentate, the environments around the metallic centres being tetrahedral, octahedral or trigonal bipyramidal. When N-H groups are involved in extra hydrogen bonding, a supramolecular architecture may be obtained

NEW SELENATO TRIPHENYLTIN (IV) AND TRIMETHYLTIN (IV) DERIVATIVES: SYNTHESIS, INFRARED AND NMR STUDIES

Five derivatives of general formulae [cation] [SeO4SnR3] (R = Ph, Me) have been studied by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy. The suggested structures are infinite chains or oligomers, the environment around the tin centre being trans trigonal bipyramidal, the phenyl and methyl substituants occupying equatorial positions, the selenate anion behaving as a bridging bidentate ligand and occupying the apical positions. When cations are involved, supramolecular architectures may be obtained

Bis(dimethyl­ammonium) tetra­chlorido­dimethyl­stannate(IV)

Regular crystals of the title compound, (C2H8N)2[Sn(CH3)2Cl4], were obtained by reacting SnMe2Cl2 with (CH3)2NH·HCl in ethanol in a 1:1 ratio. The Sn atom lies on a center of symmetry and is six-coordinated. It has a distorted octahedral SnC2Cl4 environment with the Cl atoms in cis positions. The Cl atoms are connected to dimethyl­ammonium cations through N—H⋯Cl hydrogen bonds, forming an infinite chain extending parallel to [010]

NEW PYRIDINE-3-SULFONATO TIN (IV), ANTIMONY (III) AND (V) HALO ADDUCTS AND COMPLEXES: SYNTHESIS AND INFRARED STUDY

Six new tin (IV), antimony (III) and antimony (V) adducts and complexes have been synthesized. Discrete structures were suggested on the basis of infrared data. Within the structures, the anion behaves as a bidentate, monochelating and monodentate, monodentate and tri O-chelating ligand. The environments around metallic centres are octahedral. Considering preamble of extra hydrogen bonds in compounds containing water molecules and/or OH groups, supramolecular architectures may be given rise
