TETRAKIS(N,N'-DIPHENYLBENZAMIDINATO) DICOPPER(II) DICHLOROMETHANE SOLVATE

The title compound, [Cu-2(C19H15N2)(4)].2CH(2)Cl(2), forms a cage stru cture with fourfold symmetry. The cage comprises two Cu atoms lying on the axis and four bridging ligand units related by the fourfold rotat ion. The ligand units also have approximate twofold axial symmetry. Th e Cu1-Cu2 separation of 2.460 (2) Angstrom is consistent with a single -bond distance. The metal-ligand distances, Cu1-N1 of 2.020 (5) and Cu 2-N2 of 2.027 (4) Angstrom, are effectively equal. A cavity within the structure is occupied by disordered molecules of dichloromethane solv ent.
