The room temperature X-ray single-crystal structural characterization of a protonated copper(II) complex of a ligand artefact, L', of L = N-Me(6)sar (described in an accompanying paper) is recorded, the new ligand L' being generated formally by elimination of a CH2CH2 bridge between a pair of nitrogen donor atoms of L. The complex, [ClCu(H(2)L')] (ClO4)(3).2H(2)O, is orthorhombic, Peen, a 22.528(7), b 10.544(3), c 13.748(6) Angstrom, Z = 4 formula units, R being 0.053 for 1133 independent 'observed' [I > 3 sigma(I)] reflections. The cation, containing five-coordinate square-pyramidal ClCuN4 copper, is disposed with the Cu-Cl bond [2.458(3) Angstrom] lying on a crystallographic 2 axis; Cu-N distances are 2.094(8) and 2.093(8) Angstrom.
