N2 - The new compound LiCd2(SeO3)(2)(OH) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction and IR spectroscopy. It is built up from a network of edge- and vertex-sharing pyramidal [SeO3](2-) groups, distorted CdO6 octahedra, and CdO7 monocapped trigonal prisms. The cadmium-centred groups form infinite columns, onto which Se atoms (as [SeO3](2-) groups) are grafted. Cross-linking between the columns results in a three-dimensional framework which encapsulates [100] channels occupied by the tetrahedrally-coordinated lithium cations. The H atom of the hydroxyl group appears to participate in a weak, bifurcated, hydrogen bond. Crystal data: LiCd2(SeO3)(2)(OH), M-r=502.67, monoclinic, P2(1)/c (No. 14), a=5.8184 (3) Angstrom, b=10.2790 (5) Angstrom, c=11.5021 (5) Angstrom, beta=90.446(1)degrees, V=687.89 (9) Angstrom(3), Z=4, R(F)=0.021, wR(F-2)=0.046.
