摘要：

The crystal structure of fornacite Pb-2(Cu,Fe)[CrO4(As,P)O4OH] from the Berezovskii deposit (Central Urals, Russia) was refined by X-ray powder diffraction data using the Rietveld method. Fornacite is monoclinic, space group P2(1)/c, the unit cell dimensions are a = 8.09015(12), b = 5.90913(9), c = 17.4839(2) , beta = 109.99(2), V = 785.5(3) (3), and Z = 4. The structure was refined in the isotropic approximation of the atomic displacement parameters up to R (p) = 0.0516, R (wp) = 0.0692, R (B) = 0.0229, and R (F) = 0.0200. The fornacite structure is similar to that of minerals of the brackebuschite-group and consists of heteropolyhedral chains, built by the columns of edge-sharing Cu2+O6 octahedra connected with isolated Cr6+O4 and As5+O4 tetrahedra. The chains are linked by ninefold Pb2+ polyhedra.
