Abstract

A heterometallic 3d–4f complex with hepta-nuclear hexagonal cluster, [ErZn6(μ3-O)3(μ3-C2H4NO2)6(H2O)9]6+ (C2H4NO2 = glycine) was synthesized and characterized. The cluster belongs to hexagonal crystal system. It crystallizes in the P-6 space group. In each cluster, Er3+ ion is in the center of a prism, which is composed of six zinc atoms. Er3+ ion coordinates to nine oxygen atoms. Each glycine ligand chelates to two Zn2+ and one Er3+ ions using a μ3-coordination mode. Fluorescent, thermodynamic and magnetic studies of the cluster were performed. The complex does not show single molecule magnet behavior.
