Synthesis and structural characterization of...

In the crystal structure of the title compound, [Cu₄Cl₆O(C₁₃H₉N)₄]·CH₂Cl₂, the core mol-ecular structure consists of a Cu₄ tetra-hedron with a central inter-stitial O atom. Each edge of the Cu₄ tetra-hedron is bridged by a chlorido ligand. Each copper(II) cation is coordinated to the central O atom, two chlorido ligands and one N 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.
