The preparation and characterization by X-ray crystallography of transition
metal sulfur dioxide hexafluoroarsenates of the general formula [M(SO2)(x)
](AsF6)(2) 1 (1a: M = Mn, x = 2; 1c: M = Co, x = 4; 1e: M = Cu, x = 4) and
the hexafluoroantimonate [CO(SO2)(2)](SbF6)(2) 3 is reported. The structura
l features of the compounds mentioned are compared with those of [Fe(SO2)(4
)](AsF6)(2) (1b) and [Ni(SO2)(6)](AsF6)(2) (1d), reported previously. The s
tructural diversity of transition metal sulfur dioxide complexes is discuss
