(cis-1,2-Dichlorovinyl)bis(dimethylglyoximato-N,N')(pyridine-N)cobalt(III) Chloroform Solvate, [Co(dmgH)₂(py)(CCl=CHCl)].CHCl₃

In the title complex, [Co(C₂HCl₂)(C₄H₇N₂O₂₂(C₅H₅N)].CHCl₃, the Co atom exhibits a distorted octahedral coordination with the two dimethylglyoximate (dmgH) ligands in equatorial positions [Co-N 1.891 (2)-1.897 (3) Å]. The axial positions are occupied by the pyridine (py) and cis-1,2-dichlorovinyl ligands [N-Co-C 179.0 (1)°], which are nearly coplanar. The Co-C1 distance is 1.958 (3) Å. The Co-N_py bond length of 2.028 (2) Å indicates a lower trans influence for the dichlorovinyl ligand compared with alkyl ligands.
