Proton-Conductive Polyoxometalate Architectures Constructed from Lanthanide-Incorporated Polyoxoniobate Cages

Two new extended polyoxometalate (POM) architectures based on lanthanide-incorporated polyoxoniobate (Ln-incorporated PONb) cages, namely, H4[CuII(en)2]4{K4(H2O)2[CuII(en)2]5[CuII5(trz)2(en)4 (OH)2] [Dy2CuII2(en)2(CO3)3(H2O)2(OH)3] [Dy(H2O)4] [DyNb23O68- (H2O)4]2}center dot 60H2O (1, en = ethylenediamine) and H20[CuII(en)2]4 {[CuII(en)2]4[Dy2(C2O4)(H2O)4]2[(Nb32(OH)4(H2O)3O89]2}center dot 54H2O (2), have been successfully synthesized and structurally characterized, demon-strating a feasible strategy to develop functional POM materials. In addition, the proton conductivity and magnetic behaviors of both 1 and 2 were studied.
