Tetraphenylantimony N-benzoylglycinate: synthesis and structure

Resumo

Tetraphenylantimony N-benzoylglycinate (I) has been synthesized by the reaction between pentaphenylantimony and N-benzoylglycine in toluene. According to X-ray diffraction data, the antimony atom in a molecule of complex I has a trigonal bipyramidal coordination to the oxygen atom in axial position. The Sb‒C_eq, Sb‒C_ax, and Sb‒O bond lengths are 2.116(6)‒2.138(6), 2.183(6), and 2.200(4) Å, respectively. The intramolecular Sb⋯O=C distance between the carbonyl oxygen atom and the central antimony atom is 3.35(2) Å.
