NEW HALO- AND ORGANOTIN (IV) PHENYLARSENIATO ADDUCTS AND DERIVATIVES
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2013 Four new phenylarseniato adducts and organotin derivatives have been synthesized and studied by infrared. The suggested structures are polymeric, (SnX4; X = Cl, Br) and SnPh3Cl while being discrete for SnPh2Cl(PhAsO3H)2isoBu2NH2. When OH- - - Cl, NH - - -

NEW ORGANOTIN (IV) FORMIATO ADDUCTS. SYNTHESIS AND SPECTROSCOPIC STUDIES
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2011 Five new formiato complexes have been synthesized and studied by spectroscopic methods. The structures, when the cations are involved through hydrogen bonds, are supramolecular. The anion behaves as a monocoordinating ligand. The existence of tetrahedral
