摘要：

Bright red crystals of [Mn(H2O)(6)][BiI4](2)center dot 2H(2)O are obtained from a solution of MnI2, BiI3, and I-2 in absolute ethanol, which is exposed to humid air. Reversible dehydratization sets in at about 50 C. Added water decomposes the hydrate by irreversible precipitation of BiOI. The optical bandgap is about 1.9(1) eV. X-ray diffraction on a single-crystal revealed a monoclinic lattice (space group P2(1)/c) with a = 760.39(4) pm, b = 1315.6(1) pm, c = 1398.37(7) pm, and beta = 97.438(4)degrees. In the crystal structure zigzag chains of edge-sharing [BiI2/1I4/2] octahedra and linear strings of H2O-bridged [Mn(H2O)(6)](2+) octahedra run parallel [100].
