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 , b = 12.3905(3) Ǻ , c = 8.0906(2) Ǻ , β = 134.261(1)°, Z = 4, space group Cc , which is a novel structural type of antimony(III) fluoride complex compound. The structure is formed by molecular groups SbF 3 (C 2 H 5 NO 2 )SbF 3 connected by secondary bonds into polymeric ribbons parallel to the plane ( bc ). The ribbons are connected by longer bonds Sb…F (2.674-3.177 Ǻ ) and hydrogen bonds N-H⋯F and C-H⋯F into a three-dimensional framework. Vibrational spectra of I are studied in comparison with those of crystalline γ-glycine. The biological activity of the compound of the antimony(III) fluoride complex with the amino acid is studied in vitro against the following type strains of test cultures: gram-negative bacteria ( E. coli, P. aeruginosa ), gram-positive bacteria ( S. aureus, B. subtilis ), and fungi ( C. albicans ).
