Resumen:
An electrochemical cell [Cu(+)IMeCN + H4LIPt(2)] (H4L = title ligand), yielded powdery [Cu2(L)(H2O)]n and crystalline Cu3(H2L)(L)·2H2O; the crystal structure of the latter shows an unusual helicate with an isosceles triangle core assembled by two m-phenoxo bridges [Cu···Cu 3.413(3) and 3.858(3) Å], in which tetracoordinated Cu ions are in tetrahedrally distorted square planar environments.
