Abstract

AbstractDark red single crystals of AgCuVO4 were obtained from hydroxide fluxes in Ag‐containers at 430 °C. According to X‐ray diffraction data AgCuVO4 crystallizes in the orthorhombic space group Pnma (Z = 4, a = 925.5(1) pm, b = 677.8(1) pm, c = 540.1(1) pm, wR2 = 0.0753). The Pearson code (oP28) and Wyckoff sequence (dc4a) indicate that AgCuVO4 is related to the olivine‐type of structure, but the first coordination sphere of AgI and CuII differ significantly from the C.N. 6 with irregular square‐pyramidal [AgO5] polyhedra and distorted square‐planar [CuO4] units. These differences in crystal chemistry are discussed and MAPLE as well as ECoN values are given.
