(Acetato-κO)(aqua-κO)(2-{bis­[(3,5-dimethyl-1H-pyrazol-1-yl-κN (2))methyl]amino-κN}ethanol-κO)nickel(II) perchlorate monohydrate

In the structure of the title complex, [Ni(CH(3)CO(2))(C(14)H(23)N(5)O)(H(2)O)]ClO(4)·H(2)O, the Ni(II) centre has a distorted octa­hedral environment defined by one O and three N atoms derived from the tetra­dentate ligand, and two O atoms, one from a water mol­ecule and the other from an acetate anion. The mol­ecules are connected into a three-dimensional architecture by O—H⋯O hydrogen bonds. The perchlorate anion is disordered over two positions; the major component has a site-occupancy factor of 0.525 (19).
