One new trinuclear nickel(II) cluster with a Ni3(μ 3-OH) core was synthesized by the method of in situ one pot synthesis. The complex [Ni3(μ 3-OH)(cpza)3]Cl2·H2O (1) (where Hcpza is N-(4-cyano-1H-pyrazol-3-yl)acetamide) was characterized by single-crystal X-ray diffraction methods, elemental analyses, IR spectroscopy and Hirshfeld surface analysis. For complex 1, the crystal structure is extended into 3D structure through N–H···O and O–H···Cl hydrogen bonds. According to the 3D Hirshfeld surface and 2D fingerprint plots, the main interactions in the cluster are the H···H, N···H and O···H contacts.
