Silver(I) N-Phthaloylglycinate

The title compound, Ag + .C 10 H 6 NO 4 - , was obtained by mixing N-phthaloylglycine and silver nitrate in aqueous solution. The structure is a three-dimensional network based on centrosymmetric eight-membered rings of dimeric [Ag-carboxylato-O,O'] 2 units. The Ag polyhedron is a trigonal bipyramid. Each Ag atom is linked to three carboxylic O atoms and one carbonyl O atom belonging to four N-phthaloylglycinate ligands [AgO = 2.225 (2), 2.228 (2), 2.541(2), 2.612(2) A], and to another Ag atom [Ag-Ag = 2.8465 (2) A]. This Ag-Ag interaction in the dimeric unit is short. One of the two carbonyl O atoms of the N-phthaloylglycinate ligand is not involved in the coordination polyhedron.
