Tris(ethane-1,2-diamine-κ2N,N′)nickel(II) 5-hydroxyisophthalate monohydrate

Abstract

The asymmetric unit of the title compound, [Ni(C2H8N2)3](C8H4O5)·H2O, contains one [Ni(en)3]2+ cation (en is ethane-1,2-diamine), one 5-hydroxyisophthalate dianion and one water molecule. In the cation, the Ni2+ ion is coordinated by six N atoms from three ethylenediamine ligands in a distorted octahedral geometry. The complex ions and water molecules are linked by weak N—H...N/O and O—H...N/O hydrogen bonds into a three-demensional structure.
