%X The room temperature X-ray single-crystal structural characterization of a protonated copper(II) complex of a ligand  artefact, L&#8242;, of L = N-Me6sar (described in an accompanying paper) is recorded, the new ligand L&#8242; being generated formally by elimination of a CH2CH2 bridge between a pair of nitrogen donor atoms of L. The complex, [ ClCu (H2L&#8242;) (ClO4)3.2H2O, is orthorhombic, Pccn , a 22.528(7), b 10.544(3), c 13.748(6) &#506;, Z = 4 formula units, R being 0.053 for 1133 independent 'observed' [I > 3&#963;(I)] reflections. The cation, containing five-coordinate square-pyramidal ClCuN4 copper, is disposed with the Cu- Cl bond [2.458(3)&#506;] lying on a crystallographic 2 axis; Cu-N distances are 2.094(8) and 2.093(8)&#506;.
