✦ Synopsis

The title compound, [Zn 2 (C 9 H 6 O 5 ) 2 (C 5 H 5 N) 2 ], contains pairs of pyridine-coordinated Zn 2+ ions [ZnÁ Á ÁZn = 2.987 (1) A ˚] which are bridged by two carboxylate fragments and two -O-CH 2 -CO 2 fragments of four 4-carboxylatophenoxyacetate dianions to give rise to ZnO 4 N square-based pyramids. The extended connectivity results in a layered structure.
