Synthesis, crystal structure and Hirshfeld surface analysis of a propyl 4-{[1-(2-methyl-4-nitro-phen-yl)-1-1,2,3-triazol-4-yl]meth-oxy}benzoate copper(II) chloride complex.

The core of the title complex, di-chlorido-bis-(propyl 4-{[1-(2-methyl-4-nitro-phen-yl)-1-1,2,3-triazol-4-yl]meth-oxy}benzoate)copper(II), [CuCl(CHNO)], which belongs to the copper(II) complex family, consists of two CHNO ligands and two chloride ligands arranged around the metal, forming a -di-chlorido square-planar complex. In the crystal, the mol-ecules are linked by C-H⋯Cl and C-H⋯O hydrogen bonds as well as by aromatic π-π stacking inter-actions into a three-dimensional network. To further analyse the inter-molecular inter-actions, a Hirshfeld surface analysis was performed.
