Abstract: In the Cu^II title complex, [Cu(C₂₁H₂₁N₇O₆)]·1.5CH₄O, two independent half-molecules of the title complex and one and a half methanol solvent molecules are in the asymmetric unit. The title complex possesses crystallographic C₂ symmetry. One methanol molecule is disordered around a twofold axis. The title complex geometry agrees well with that of the dihydrate determined earlier with the exception of an N-Cu-N angle deviating by almost 10°. The Cu^II centre is in a distorted square-pyramidal geometry, and intermolecular hydrogen bonds stabilize the molecular packing.
