摘要：

An electrochemical cell [Cu(+)\MeCN + H4L\Pt(-)] (H4L = title ligand), yielded powdery [Cu-2(L)(H2O)](n) and crystalline Cu-3(H2L)(L). 2H(2)O; the crystal structure of the latter shows an unusual helicate with an isosceles triangle core assembled by two mu-phenoxo bridges [Cu ... Cu 3.413(3) and 3.858(3) Angstrom], in which tetracoordinated Cu ions are in tetrahedrally distorted square planar environments.
