Bis(pyrimidine‐2‐thiolato‐N,S)bis(trimethyl phosphite‐P)cobalt(III) hexafluorophosphate

The title complex, [Co(C 4 H 3 N 2 S) 2 {P(OCH 3 ) 3 } 2 ]PF 6 , with mixed N-heterocyclic thiolate and trimethyl phosphite ligands, was synthesized and characterized by X-ray crystallography and spectroscopic measurements. The Co III ion is six-coordinated and has a slightly distorted octahedral geometry, being coordinated to two pairs of N and S atoms of two monoanionic bidentate pyrimidine-2-thiolate ligands and the P atom of each of two monodentate trimethyl phosphite ligands, with three pairs of essentially equal bonds distances [Co-N 1.968 (6) and 1.976 (5) A, Co-P 2.174 (2) and 2.177 (2) A, and Co-S 2.279 (2) and 2.282 (2) A].
