Description
Summary:In the title compound, [Zn(C14H17N5O3)(C9H4O6)(H2O)2]·H2O, the complex molecule exists in a zwitterionic form. The ZnII ion exhibits a distorted tetragonal-pyramidal geometry, being coordinated by two O atoms from the zwitterionic 8-ethyl-5-oxo-2-(piperazin-4-ium-1-yl)-5,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylate (L) ligand, one O atom from the 5-carboxybenzene-1,3-dicarboxylate dianion, [Hbtc]2−, and two O atoms from two aqua ligands. In the crystal, N—H...O and O—H...O hydrogen bonds link the components into a three-dimensional structure. The crystal packing exhibits π–π interactions between the aromatic rings, with centroid–centroid distances in the range 3.466 (3)–3.667 (3) Å.
