(Di-2-pyridyl-amine)-(methanol)sulfato-copper(II)

The title complex, [Cu(SO(4))(C(10)H(9)N(3))(CH(3)OH)], is a mononuclear species with the Cu(II) ion in a Jahn-Teller-distorted '4 + 1' square-pyramidal geometry. The basal plane is defined by the pyridyl N-atom donors of the bipyridyl-amine (bpa) ligand and two O-atom donors of the sulfate ligand. The coordination geometry is completed by the axial coordination of a methanol O-atom donor. The axial bond length displays the usual elongation: Cu-O(axial) = 2.168 (2), Cu-O(basal) = 2.016 (2) (average) and Cu-N(basal) = 1.951 (3) Å (average). In the crystal structure, the complex mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen bonds into chains along [100].
