Nuclearity control of a trisaloph zinc cluster complex dependent on minute structural differences in the bridging anions.

The Zn(6) cluster complex 2 of the trisaloph ligand was synthesized using EtCO(2)(-) anions as bridging ligands. Complex 2 has a dimeric structure in the crystalline state, while two monomeric isomers were in equilibrium in solution. The anion-exchange reaction successfully resulted in nuclearity control from Zn(7) to Zn(6).
