摘要：

A single crystal X-ray structure investigation of hydrothermally synthesized K4Cu3[AsO4](2)[AsO3(OH)](2) proved P2(1)/c symmetry (a = 9.498(3), b = 9.992(3), c = 9.630(3) Angstrom, beta = 118.27(2)degrees, Z = 2; R = 0.031, R(w) = 0.021 for 2613 reflections with F-o > 3 sigma(F-o) up to sin theta/lambda = 0.81 Angstrom(-1)). Cu-[4] and Cu-[4+1] atoms are connected via O atom corners to triple groups which are interconnected by arsenate tetrahedra to yield a two-dimensional arrangement. These layers are linked by the K atoms and by a short, but symmetrically not restricted hydrogen bond: O-H...O = 2.479(3) Angstrom.
