SILVER(I) N-PHTHALOYLGLYCINATE

The title compound, Ag+.C10H6NO4-, was obtained by mixing N-phthaloylg lycine and silver nitrate in aqueous solution. The structure is a thre e-dimensional network based on centrosymmetric eight-membered rings of dimeric [Ag-carboxylato-O,O'](2) units. The Ag polyhedron is a trigon al bipyramid. Each Ag atom is linked to three carboxylic O atoms and o ne 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 d imeric unit is short. One of the two carbonyl O atoms of the N-phthalo ylglycinate ligand is not involved in the coordination polyhedron.
