One Novel Trinuclear Nickel(II) Cluster Containing a Pyramidal Ni-3(mu(3)-OH) Core: Crystal Structure and Hirshfeld Surface Analysis

摘要

One new trinuclear nickel(II) cluster with a Ni-3(mu(3)-OH) core was synthesized by the method of in situ one pot synthesis. The complex [Ni-3(mu(3)-OH)(cpza)(3)]Cl-2 center dot 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 center dot center dot center dot O and O-H center dot center dot center dot Cl hydrogen bonds. According to the 3D Hirshfeld surface and 2D fingerprint plots, the main interactions in the cluster are the H center dot center dot center dot H, N center dot center dot center dot H and O center dot center dot center dot H contacts.
