Abstract

The title structure, [Ni(C14H8N2O4)(H2O)4]·4H2O, contains a mononuclear NiII complex formed by a chelating bidentate Schiff base and by four Ni-bonded water mol­ecules. The NiII atom is in a distorted octa­hedral coordination by two N atoms in a cis disposition [Ni—N = 2.0753 (16) and 2.1048 (16) Å] and by four water O atoms [Ni—O = 2.0500 (15)–2.0822 (15) Å]. The crystal structure is completed by four further non-coordinating water mol­ecules and all constituents are linked in a three-dimensional manner by an extensive system of 16 O—H⋯O hydrogen bonds.
