A new heptanuclear trigonal prismatic cluster [PrCu6(μ3-OH)3(Gly)6im6](ClO4)6 was synthesized through the self-assembly of Pr3+, Cu2+, glycine and imidazole in aqueous solution and characterized by X-ray structure analysis. The compound belongs to the trigonal R3 space group with a = b = 15.8761(2), c = 23.4943(5) ?, V = 5128.4(1) ?3, Z = 3, Dc = 1.965 g/cm3, μ = 2.869 mm-1, F(000) = 3012, the final R = 0.0332 and wR = 0.0844 for 3596 independent reflections. In the cation, the Pr3+ ion is situated at the center of a prism formed by six copper atoms and coordinates to nine oxygen atoms with a tricapped trigonal prismatic coordination polyhedron. Six glycine ligands and six imidazole terminal ligands participate in constructing the cluster.
