Abstract
In the crystal structure of the title compound, [Cu4Cl6O(C13H9N)(4)]center dot CH2Cl2, the core molecular structure consists of a Cu-4 tetrahedron with a central interstitial O atom. Each edge of the Cu-4 tetrahedron 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-phenylethynylpyridine ligand. In the crystal, the molecules are linked by intermolecular C-H center dot center dot center dot Cl interactions. Furthermore, C-H center dot center dot center dot pi and pi-pi interactions also connect the molecules, forming a three-dimensional network. Hirshfeld surface analysis indicates that the most important contributions for the packing arrangement are from H center dot center dot center dot H and C center dot center dot center dot H/H center dot center dot center dot C interactions.
