Resumen
Neutral bi- and mono-nuclear dicyanotriazolate (DcTz) complexes of formulae [Rh2(μ-DcTz)2L2L′2] (L2 = L′2 = diolefin; L = CO, L′ = PPh3 or P(OPh)3; L = L′ = P(OPh)3; L2 = COD, L′ = P(OPh)3) and [Rh(DcTz)L2L′] (L2 = diolefin, L′ = PPh3; L = PPh3, L′ = CO) and the ionic derivative [Rh(dppe)2][DcTz] have been prepared. New heteroatom-bridged complexes of formula [Rh2(μ-DcTz)(μ-X)(COD)L2] (L2 = COD, L = CO) have been obtained by treating [Rh2(μ-DcTz)2(COD)2] with [Rh2(μ-Cl)2(L2)2] (X = Cl), or (X = N3) by subsequent treatment with NaN3. The properties of [Rh2 (μ-DcTz)(μ-N3)(COD)(CO)2] and the related derivative, [Rh2(μ-DcTz)(μ-N3)(CO)4] indicate the presence of intermolecular interactions. Some oxidative addition reactions of I2, IMe and HgCl2 to [Rh2[μ-DcTc)2(CO)2(PPh3)2] have been examined. © 1988.
