Abstract
The crystal structures of isostructural fluoride complexes of indium(III) M[InF4(H2O)2] (M = Rb, Cs) crystallizing in the monoclinic system, space group I2/a, are studied. The structures of M[InF4(H2O)2] (M = Rb, Cs) are formed of isolated centrosymmetric complex [InF4(H2O)2]– anions with the trans-position of coordinated H2O molecules and Rb+, respectively Cs+, cations. The In atom in the complex [InF4(H2O)2]– anion is surrounded by four F atoms and two oxygen atoms of coordinated H2O molecules, forming the coordination polyhedron as a slightly distorted octahedron. Via a system of hydrogen O–H⋯F bonds the polyhedra of In atoms are arranged in a three-dimensional framework with the cations located in its channels.
