trans-Chlorido­tetra­kis­(4-methyl­pyridine-κN)(nitrosyl-κN)ruthenium(II) bis­(hexa­fluorido­phosphate) acetone 0.75-solvate

The title compound, [RuCl(NO)(C6H7N)4](PF6)2·0.75(CH3)2CO, comprises four ligands of 4-picoline in equatorial position around the central atom. Overall, the complex features an octa­hedral coordination environment around the central RuII atom, with the chlorido ligand trans to the nitrosyl. The bond length of the nitrosyl N=O ligand is 1.140 (5) A, while the angle Ru—N=O is 179.0 (4)°. The asymmetric unit contains four PF6− counter-anions, two with occupancy of 0.25 and one with occupancy of 0.5. One PF6− anion is disordered over two sets of sites and one other is disordered with an acetone mol­ecule that occupies the same site.
