Isostructural fluorooxalate complex compounds of indium(III) M[InF(CO)HO] (M = K, Rb), being the first representatives of a new class of mixed-ligand fluoro-containing complex compounds of indium(III) are synthesized and structurally studied for the first time. The crystal structures of M[InF(CO)HO] (M = K, Rb) are formed of K cations (Rb respectively) and complex [InF(CO)HO] anions. The indium atom in the complex anion is surrounded by four F atoms, two of which are bridging, the oxygen atom of the coordinated HO molecule, and two oxygen atoms of the bis-bidentate (tetradentate) oxalate group. The coordination polyhedron of the indium atom (CN 7) is a pentagonal bipyramid. Via alternating double bridging F atoms and tetradentate bridging CO group, the In(III) atom polyhedra are arranged in polymers chains. Via hydrogen O-H⋯F bonds the chains are organized in layers. Between the layers, the K or Rb cations are located, which strengthen the crystal structure. [ABSTRACT FROM AUTHOR]
