SILVER(I) N-PHTHALOYLGLYCINATE

The title compound, Ag+.C10H6NO4-, 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 [Ag-O = 2.225(2), 2.228(2), 2.541 (2), 2.612(2) Angstrom], and to another Ag atom [Ag-Ag = 2.8465 (2) Angstrom]. 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.
