Fixation of triruthenium clusters on melamine: synthesis and structure of [Ru-3(mu(2)-H)(CO)(9){mu(3),eta(2)-NHC3N3(NH2)(2)}], cis-[{Ru-3(mu(2)-H)(CO)(9)}(2){mu(3),eta(2):mu(3),eta(2)-NHC3N3(NH2)}] and trans-[{Ru-3(mu(2)-H)(CO)(9)}(2){mu(3),eta(2):mu(3),eta(2)-NHC3N3(NH2)}]

Melamine, C3N3(NH2)(3), was found to react with [Ru-3(CO)(12)] to give, with N-H activation, the monometallated derivative [Ru-3(mu(2)-H)(CO)(9){mu(3),eta(2)-NHC3N3(NH2)(2)}] (1) and the two isomeric bimetallated derivatives cis-[{Ru-3(mu-H)(CO)(9)}(2){mu(3),eta(2) : mu(3),eta(2) - NHC3N3(NH2)}] (cis-2) and trans-[{Ru-3(mu-H)(CO)(9)}(2){mu(3),eta(2) : mu(3),eta(2)-NHC3N3(NH2)}] (trans-2). The molecular structures of 1, cis-2 and trans-2 have been determined by single-crystal X-ray crystallography. (C) 1998 Elsevier Science S.A.
