Synthesis and crystal structure of In(OH)(SeO3)

In(OH)(SeO3), prepared by a hydrothermal reaction, crystallizes in a new structure type containing cis InO4(OH)(2) octahedra. These groups share both corners (via OH) and edges (via 0) to result in a layered motif containing octahedra) 8-ring holes that resembles a single layer of the hollandite structure. The selenium atoms [as pyramidal (SeO3)(2-) selenite groups] decorate the 8-ring holes and crosslink the sheets, leading to a three-dimensional structure. Crystal data: In(OH)(SeO3), M-r = 258.79, triclinic, P1 (No. 2), a = 5.6523 (2)angstrom, b = 7.9598 (3)angstrom, c = 8.0911 (3)angstrom, alpha = 87.925 (2)degrees, beta = 79.679 (2)degrees, gamma = 83.201 (3)degrees, V = 355.58 (2)angstrom(3), Z = 4, R (F) = 0.023, wR (F-2) = 0.054.
