Bis(di-2-pyridylphosphinato-kappa3N,O,N')copper(II) dichloromethane disolvate.
The solid-state structure of the first reported homoleptic copper di-2-pyridylphosphinate complex shows an extremely large 'z-out' tetragonal distortion, with an axial Cu.O distance of 2.430 (2) A. The title complex, [Cu(C(10)H(8)N(2)O(2)P)(2)].2CH(2)Cl(2) or Cu[py(2)P(O)O](2).2CH(2)Cl(2), comprises two di-2-pyridylphosphinate ligands coordinated to the central copper(II) ion, which sits on an inversion center. The pyridyl rings of one ligand are trans to the pyridyl rings of their symmetry-related counterpart. The two trans py-Cu-py moieties are coplanar, as required by the inversion symmetry. A disordered dichloromethane solvent molecule is cocrystallized in the asymmetric unit cell.
