Abstract: The structure of the title compound, {[Cu(C₁₁H₁₉N₄O₂)(H₂O)_0.5]ClO₄}_n, consists of perchlorate anions and infinite chain cations. Each Cu atom has a distorted square-pyramidal or octahedral environment, with two oxime and two imine N atoms from the tetradentate ligand in a square-planar arrangement and one or two weak bonds to O atoms in trans positions through the coordination of the half-occupancy water molecule and an oxime O atom of the adjacent unit. The dihedral angle between the planes of coordination of the tetradentate ligand in adjacent units of the polymeric cation is 61.92 (4)°. The perchlorate anions are hydrogen bonded to the aqua ligand.
