The title complex, [Cu(SO₄)(C₁₀H₉N₃)(CH₃OH)], 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 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—HO and O—HO hydrogen bonds into chains along [100].
