The title complex, [Cu(C8H18NO5)Cl] or [Cu(H4bis-tris)Cl], was obtained starting from the previously reported [Cu(H5bis-tris)Cl]Cl compound. The deprotonation of the aminopolyol ligand H5bis-tris {[bis(2-hydroxyethyl)amino]tris(hydroxymethyl)methane, C8H19NO5} promotes the formation of a very strong O—H...O intermolecular hydrogen bond, characterized by an H...O separation of 1.553 (19) Å and an O—H...O angle of 178 (4)°. The remaining hydroxy groups are also engaged in hydrogen bonds, forming R22(8), R44(16), R44(20) and R44(22) ring motifs, which stabilize the triperiodic supramolecular network.
