摘要：

Aluminium dicopper arsenate tetrahydroxide tetrahydrate, Cu2Al(AsO4)(OH)4.4H2O, M(r) = 433, monoclinic, I2/a, a = 12.664 (2), b = 7.563 (2), c = 9.914 (3) angstrom, beta = 91.32 (2)-degrees, V = 949.4 (3) angstrom 3, Z = 4, D(x) = 3.04 g cm-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 84.9 cm-1, F(000) = 848, T = 297 K, R = 0.027 for 1215 observed reflections. The structure is a heteropolyhedral framework of [AsO4] tetrahedra, [CuO2-(OH)2(H2O)2] octahedra and [AlO2(OH)4] octahedra.
