title: Hydroxonium creatininium bis-(pyridine-2,6-dicarboxyl-ato-κO,N,O)nickel-ate(II) trihydrate.
abstract: The title compound, (C(4)H(8)N(3)O)(H(3)O)[Ni(C(7)H(3)NO(4))(2)]·3H(2)O, exhibits isotypism with its Co(II) analogue. All intramolecular distances and angles are similar for the two structures. This applies also for the intermolecular forces, consisting of O-H⋯O and N-H⋯O hydrogen bonds and π-π interactions [with centroid-centroid distances of 3.428 (2) and 3.579 (2) Å], that lead to a cohesion of the structure.
