| 摘 要： | A new heptanuclear trigonal prismatic cluster PrCu6(μ3-OH)3(Gly)6im6](ClO4)6 was synthesized through the self-assembly of Pr^3 , Cu^2 , glycine and imidazole in aqueous solution and characterized by X-ray structure analysis. The compound belongs to the trigonal R3 space groupwith a=b=15.8761(2), c=23.4943(5) A, V=5128.4(1)A^3, Z=3, Dc=1.965 g/cm^3,μ=2.869mm^-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.

| Abstract: | A new heptanuclear trigonal prismatic cluster PrCu6(μ3-OH)3(Gly)6im6](C1O4)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) (A), V = 5128.4(1) (A)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. |
