Synthesis and ligand substitution of tetrakis(alkylisocyanide) bis(tri-2-furylphosphine)-cobalt(iii) complexes
The complexes [Co(CNC 6 H 11 ) 4 {P(C 4 H 3 O) 3 } 2 ](ClO 4 ) 3 and [Co(CNCH 2 Ph) 4 {P(C 4 H 3 O) 3 } 2 ](BF 4 ) 3 have been synthesized by ligand substitution of tri-2-furylphosphine in the intermediate-spin complexes [Co(CNC 6 H 11 ) 4 (OSbPh 3 ) 2 ](ClO 4 ) 3 and [Co(CNCH 2 Ph) 3 (OSbPh 3 ) 2 ]...
