The cobalt(II) complex [Co(DMSO)6](BPh4)2 (DMSO = dimethylsulfoxide) was prepared, and characterized by single-crystal X-ray method. The compound crystallizes in the triclinic space group P1 and Z = 2 with cell parameters a = 12.551(2)Å, b = 13.087(2)Å, c = 21.491(3)Å, α = 88.818(4)°, β = 74.243(3)°, γ = 64.296(3)°, V = 3041.9(9)Å3. Six DMSO molecules coordinate to a cobalt(II) center to form a [Co(DMSO)6]2+ cation, which can be approximated to an S6 point group. However, the coordination geometry can be best described as a pseudo-C2v symmetry with elongation along the O-Co-O axis.
