Syntheses of tris(t-butylisocyanide)bis(tri-p-dimethyl- aminophenylphosphine)cobalt(I) and cobalt(II) perchlorates: a reversal of the usual stabilities of cobalt oxidation states

The complexes [Co(CNCMe 3 ) 3 {P(C 6 H 4 NMe 2 -p) 3 } 2 ](ClO 4 ) 2 and [Co(CNCMe 3 ) 3 {P(C 6 H 4 NMe 2 -p) 3 } 2 ]ClO 4 are reported. The Co(II) complex, formed by reaction of excess triarylphos-phine with the alkylisocyanide Co(II) complex, is stable and the favoured product. The Co(I) complex,...

More Information
Summary:The complexes [Co(CNCMe 3 ) 3 {P(C 6 H 4 NMe 2 -p) 3 } 2 ](ClO 4 ) 2 and [Co(CNCMe 3 ) 3 {P(C 6 H 4 NMe 2 -p) 3 } 2 ]ClO 4 are reported. The Co(II) complex, formed by reaction of excess triarylphos-phine with the alkylisocyanide Co(II) complex, is stable and the favoured product. The Co(I) complex, formed by hydrazine reduction of the Co(II) complex, has limited stability in solution, readily oxidizing to the Co(II) species. Upon prolonged irradiation of the Co(II) complex in acetone, [Co{OP(C 6 H 4 NMe 2 -p) 3 } 4 ](ClO 4 ) 2 is produced.
