Description
Summary:New double complexes [Co(DMSO) 6 ][SiF 6 ] ⋅ 2H 2 O ( I ) and [Co(DMF) 3 (H 2 O) 3 ][SiF 6 ] ⋅ DMF ( II ) have been synthesized and studied by IR spectroscopy and X-ray diffraction. Crystals of complex I belong to the tetragonal symmetry system, space group R 3̄, Z = 3, a = 11.8232(3) Å, c = 18.4699(5) Å, V = 2235.97(10) Å 3 , ρ calc = 1.573 g/cm 3 . Crystals of complex II are triclinic, space group P 1̄, Z = 2, a = 8.6264(4) Å, b = 10.1419(4) Å, c = 13.9657(6) Å, α = 100.847(2)°, β = 98.549(2)°, γ = 93.479(2)°, V = 1181.71(9) Å 3 , ρ calc = 1.539 g/cm 3 .
