Synthesis, crystal structure and Hirshfeld surface analysis of di-μ-iodido-bis-[(2,2'-bi-quinoline-κ ,')copper(I)].

The mol-ecular and crystal structures of the title compound, [CuI(CHN)], were examined by single-crystal X-ray diffraction and Hirshfeld surface analysis. The Cu atom is coordinated in a distorted tetra-hedral geometry by two N atoms from the 2,2'-bi-quinoline ligands and the two μ-bridging iodide ligands. The mol-ecules are in contact π-π-stacking inter-actions. Hirshfeld surface analysis showed that the most important contributions to the inter-molecular inter-actions are H⋯H (39.7%), H⋯I/I⋯H (17.8%), C⋯H/H⋯C (17.5%), C⋯C (16.5%), N⋯C/C⋯N (3.9%) and N⋯H/H⋯N (3.5%).
