Stabilization of the (eta(4)-COD)Pt-fragment (COD = eta(2),eta(2)-cyclo-octa-1,5-diene) by a bistriazenide: Synthesis and X-ray structural characterization of [(eta(4)-COD)Pt(NNN-Ph)(2)C6H4], a neutral 1,2-bis(phenyltriazenido)benzene complex of plat

摘要

After exchange of Cl against NO3 by reaction with AgNO3 [(COD)PtCl2] reacts with the sodium salt of 1,2-bis(phenyltriazene)benzene to give [(eta(4)-COD)Pt(NNN-Ph)(2)C6H4], the first example of a pi-fragment of platinum(II) stabilized by two symmetrical triazenide chains. The new complex belongs to the monoclinic space group C2/c and corroborates the ability of the (COD)Pt fragment to be stabilized by bidentate ligands. The odd flying dragon structure of the title compound retains the C-2v symmetry of the free anion 1,2-bis(phenyltriazenide)benzene. (c) 2005 Elsevier B.V. All rights reserved.
