Synthesis and structural characterization of hexa-μ-chlorido-μ-oxido-tetra-kis-{[4-(phenyl-ethyn-yl)pyridine-κ]copper(II)} di-chloro-methane monosolvate.

In the crystal structure of the title compound, [CuClO(CHN)]·CHCl, the core mol-ecular structure consists of a Cu tetra-hedron with a central inter-stitial O atom. Each edge of the Cu tetra-hedron is bridged by a chlorido ligand. Each copper(II) cation is coordinated to the central O atom, two chlorido ligands and one atom of the 4-phenyl-ethynyl-pyridine ligand. In the crystal, the mol-ecules are linked by inter-molecular C-H⋯Cl inter-actions. Furthermore, C-H⋯π and π-π inter-actions also connect the mol-ecules, forming a three-dimensional network. Hirshfeld surface analysis indicates that the most important contributions for the packing arrangement are from H⋯H and C⋯H/H⋯C inter-actions.
