摘要：
A new compound, K8Nb7As7O39, has been synthesized by solid-state reaction. It crystallizes in the triclinic system, space group P (1) over bar with unit-cell parameters a = 8.767(4)angstrom, b = 12.260(4)angstrom, c = 19.018(4)angstrom, alpha = 106.530(2)degrees, beta = 99.470(2)degrees, gamma = 90.460(2)degrees and Z = 2. The structure of the compound is solved and refined to R = 0.062 and.R2 = 0.1540. The structural study of K8Nb7As7O39 shows that the compound has a two-dimensional framework.
