title: (Acetato-κO)(aqua-κO)(2-{bis-[(3,5-dimethyl-1H-pyrazol-1-yl-κN(2))methyl]amino-κN}ethanol-κO)nickel(II) perchlorate monohydrate.
abstract: 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 octa-hedral environment defined by one O and three N atoms derived from the tetra-dentate ligand, and two O atoms, one from a water mol-ecule and the other from an acetate anion. The mol-ecules 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).
