Brief Communication


In this article, we described the structural studies of Ru(II) compound containing pyrazole ligands. On the basis of structural analysis, the complex exhibit non-covalent C–H···Cl interaction. Hirshfeld surface analysis showed that the structure of compound is mainly characterized by Cl···H, and O···H contacts but other contribution was also observed from Cl···O and C···H contacts. DFT calculation show that theoretical bond lengths and bond angles are in good agreements with the experimental values obtained from single crystal x-ray crystallography.

Graphic Abstract
