Abstract
A new indium(III) fluoride complex Cu(InF4)2·10H2O with the divalent Cu2+ cation is synthesized for first time, and its crystal structure, which is a new type of the structure of complex fluorides of trivalent metals with divalent cations, obtained from a hydrofluoric acid solution, is studied. The structure of Cu(InF4)2·10H2O is monoclinic, space group P21/a. The structure is formed by isolated centrosymmetric distorted octahedral complex [Cu(H2O)6]2+ cations and isolated distorted octahedral complex [InF4(H2O)2]– anions with the cis arrangement of coordinated water molecules. The branched system of O–H·F hydrogen bonds, which is formed by the coordinated H2O molecules with the F atoms of anions, combines the structural elements of the compound to form a three-dimensional framework.
