Abstract
The title complex, [Cu(SO4)(C10H9N3)(CH3OH)], is a mononuclear species with the CuII ion in a Jahn–Teller-distorted ‘4 + 1’ square-pyramidal geometry. The basal plane is defined by the pyridyl N-atom donors of the bipyridylamine (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 molecules are linked through N—H⋯O and O—H⋯O hydrogen bonds into chains along [100].
