ABSTRACT
The iminodiacetate dianion in the title compound, [Zn(C4H5NO4)(C12H8N2)(H2O)]·1.5H2O, chelates to the ZnII center with its N and two O atoms. The metal atom is also chelated by the N-heterocycle and coordinated by one water molecule, leading to a distorted octahedral environment. The dianion, and coordinated and uncoordinated water molecules interact through O—H...O hydrogen bonds, generating a three-dimensional network. One of the two uncoordinated water molecules has half-site occupancy. The crystal studied was a non-merohedral twin with a 15% twin component.
