No full text2(Cy2NH2)2SO4Sn(SO4)2Cy2NH2Cl and 2(Cy2NH2)2SO4. Sn(SO4)22Cy2NH2Cl complexes have been obtained on allowing Cy2NH2O2C-SO3H and Cy2NH2HSO4 to react respectively with SnBu2Cl2 and SnBu3Cl in specific ratios.The molecular structures of these compounds have been determined on the basis of the infrared data. The suggested structures are dimeric, the tin atom being octacoordinated by four chelating sulfate anions, the monomeric basic entities being connected by hydrogen bonded cation chloride cation strings
Et2NH2C6H3(CO2)3SnBr2.4H2O: SYNTHESIS AND INFRARED STUDY
No full textThe title compound has been obtained on allowing [C6H3(CO2)3(Et2NH2)3] to react with SnBr4. The molecular structure of Et2NH2C6H3(CO2)3SnBr2.4H2O has been determined on the basis of the infrared data. The suggested structure is a dimer in which each tin atom is hexacoordinated by two chelating C6H3(CO2)33- anions and two Br atoms. Cy2NH2+cations are involved through hydrogen bonds with non-coordinating CO2 groups. The suggested structure is a cage
(Cy2NH2)2SO4.2SnMe3SO4Cy2NH2; 2(Cy2NH2)2SO4.5SnMe3SO4Cy2NH2: SYNTHESIS AND INFRARED STUDY
No full textAllowing (Cy2NH2)2.SO4.2H2O or Cy2NH2.HSO4 to react with SnMe3Cl in ethanolic media in two specific ratios the sulphato complexes (mentioned in this paper title) were obtained and their infrared study was carried out. Discrete structures containing the complex-anion [SO4(SO4SnMe3)2]4- consisting of a central bidentate sulphate linked to SnMe3 groups which are then coordinated to monodentate sulphate anions or the complex-anion [(SO4)6(SnMe3)5]7- consisting of planar SnMe3 groups, monodentate or bidentate sulphate anions, these complex-anions dimerizing through cations via hydrogen bonds, are suggested

The molecular structures of these compounds have been determined on the basis of infrared and NMR data. The suggested structures are discrete, dimers and tetramer, the tin atom being tetra-, penta- and hexacoordinated; the benzyl carboxylate anions are monodentate, bidentate and chelating and the cations involved in hydrogen bonds
SYNTHESIS AND INFRARED STUDY OF SOME SULFATO TRIORGANOTIN DERIVATIVES AND ADDUCTS
No full textOn allowing ethylenediammonium sulfate or Me4NSO4H to react with SnPh3Cl or SnBu2Cl2 in ethanolic media in specific ratios the three sulfato complexes were obtained and their infrared study carried out. The molecular structures of these compounds have been proposed on the basis of the infrared data. Discrete structures are suggested: the sulfate anion is tetradentate in two of them and monodentate in the other, the tin center being in a trigonal bipyramidal environment in all the structures. When the ethylenediammonium ion is involved through hydrogen bonds, dimeric structures may be obtained
SYNTHESIS, INFRARED AND NMR STUDIES OF SOME SULFATO DIORGANOSTANNIC DERIVATIVES
No full textEthylendiammoniumSO4•SnBu2Cl2•1/4ethylendiammoniumCl2 (A), 2ethylendiammoniumSO4•SnBu2Cl2 (B) and Cy2NH2SO4H•Cy2NH2SnBu2Cl3 (C) complexes have been obtained on allowing ethylendiammoniumSO4 and Cy2NH2HSO4 to react respectively with SnBu2Cl2 in specific ratios. The molecular structures of these compounds have been determined on the basis of infrared and NMR data. The suggested structures are dimeric and tetrameric, the tin atom being hexacoordinated, the sulphate anions behaving as a monochelating ligand or non-coordinating and only involved in hydrogen bonds. The hydrogenosulfate is a non-sigma coordinating anion but only involved in hydrogen bonds of acetic acid type or NH…O bonds. The presence of dimeric [(SnBu2Cl3)2]2- in one of the structures is noteworthy. The key role of the cations involved in hydrogen bonds is outlined

No full textOn allowing Me4NO2CSO3H (in water) to react with SnCl4 (in ethanol) the studied complex is obtained. The suggested structure is discrete, the anion behaving as a polydentate and chelating ligand, the environment around tin being octahedral
Bis(dicyclohexylammonium) sulfate dihydrate
No full textIn the title dihydrate salt, 2C12H24N+·SO42−·2H2O, the cation possesses twofold rotational symmetry, with the N atom situated on the twofold axis. The sulfate anion has fourfold roto-inversion symmetry, with the S atom located on the -4 axis. In the crystal, the components are linked via ammonium–sulfate N—H...O and water–sulfate O—H...O hydrogen bonds, forming a three-dimensional network
