Structure and Properties of the Molecular Complex of Antimony(III) Fluoride with γ-Glycine
A binuclear complex of composition 2SbF 3 ·(C 2 H 5 NO 2 ) ( I ) of antimony(III) with the γ-glycine amino acid is prepared. The antimony atoms in this complex are connected to each other by the amino acid ligand. The crystal structure of this complex is determined to be monoclinic, a = 11.5155(3) Ǻ...
