Abstract

Bright red crystals of [Mn(H2O)6][BiI 4]2·2H2O are obtained from a solution of MnI2, BiI3, and I2 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 P21/c) with a = 760.39(4) pm, b = 1315.6(1) pm, c = 1398.37(7) pm, and β = 97.438(4)°. In the crystal structure zigzag chains of edge-sharing [BiI2/1I 4/2]- octahedra and linear strings of H 2O-bridged [Mn(H2O)6]2+ octahedra run parallel [100].
