Cobalt complexes with bulky perfluorinated alkyl ligands. Synthesis, characterization, and molecular structure of trans-bis(dimethylglyoximato)(pyridine)(F-isopropyl)cobalt(III)

The preparation of pyCo(DH) 2 [CF(CF 3 ) 2 ] (1) from Na[pyCo(DH) 2 ] and (CF 3 ) 2 CFI is described, where py=pyridine and DH=the monoanion of dimethylglyoxime. The CO(I) anion reagent is prepared from pyCo(DH) 2 Cl and 0.25 molar equiv of NaBH 4 . Complex 1 crystallizes in the monoclinic space group P2 1 /m
