Structural diversity in silver salts of hexahalogenocarborane anions, Ag(CB11H6X6) (X = Cl, Br or I)

Crystal structures have been determined for three Ag(CB 11 H 6 X 6 ) compounds (X = Cl, Br or I) crystallized from arene solvents. They are all one-dimensional co-ordination polymers in the solid state with hexahalogenocarborane anions acting as bridging ligands. The co-ordination geometries of these three salts are, however, unique. The type and number of donors to silver(I) varies from one to another and is not particularly predictable.
