Abstract: The hydrothermal reaction of V2O5, Cu(CH3COO)2·H2O, TMAOH and 1,2-diaminopropane gave a novel three-dimensional framework material, {[Cu(1,2-pn)2]4[V18O42(H2O)]}n ·8nH2O, which was constructed from the mixed-valence {V18O42(H2O)} clusters interconnected through {Cu(1,2-pn)2} complex groups.{[Cu(1,2-pn)2]4[V18O42(H2O)]}n ·8nH2O was characterized by IR, TGA and single-crystal X-ray diffraction.It crystallizes in tetragonal space group P4/nnc with a=1.5107(2) nm, c = 1.8645(4) nm, Dc = 2.028 g/cm3, Z = 2, R1= 0.0631, wR2 = 0.1538.
