The heptadentate, 'tritopic' ligand 2poapH(2) reacts with Cu(NO3)(2) in the
presence of Gd(NO3)(3) to give a novel, self-assembled, ferromagnetically
coupled, alkoxide bridged octanuclear Cu(ii) cluster in the shape of a pin-
wheel, with a central Cu-4[mu -O-4] core, and isolated Curie-like [Gd(NO3)(
4)(H2O)(2)](-) anions.
