I. Uçar and A. Bulut

Abstract: In the title compound, [Ni(C₄H₁₂N₂O)₂](C₄O₄)·H₂O or [Ni(Hydet-en)₂](Sq)·H₂O, where Hydet-en is N-(2-hydroxyethyl)ethylenediamine and Sq is the squarate dianion, the Ni^II centre has a distorted octahedral coordination geometry comprising four amine N and two hydroxyl O atoms from two tridentate Hydet-en ligands. All the O atoms of the squarate dianion are involved in N-HO and O-HO hydrogen bonding.
