Description Reaction of [{Ru(eta (3):eta (3)-C10H16)(mu -Cl)Cl}(2)] with 4-cyanopyridine (referred hereafter as (CNPy) in dichloromethane in 1:2 and 1.1 molar ratio gives mononuclear complex [Ru(eta (3):eta (3)-C10H16)Cl-2(CNPy) (1) and binuclear complex [{Ru(eta (3):eta (3)-C10H16)Cl-2}(2)(mu -CNPy)] (2) in quantitative yield. The mononuclear complex 1 reacts further with the chloro bridged arene Ru(II) complexes [{Ru(eta (6)-C6H6)(mu -Cl)Cl}(2)], [{Ru(eta (6)-C10H14)(mu -Cl)Cl}(2)], [{Ru(eta (6)-C6Me6)(mu -Cl)Cl}(2)] and the rhodium complex [{Rh(eta (5)-C5Me5)(mu -Cl)Cl}(2)], to form Ru(IV)-Ru(II) or Ru(IV)-Rh(III) binuclear complexes, in which the respective metal centers are bridged by a 4-cyanopyridine ligand. The reaction products have been characterized by microanalyses and spectroscopic studies (IR,H-1-, C-13-NMR and FAB mass spectra). The structure of the complex [Ru(eta (3):eta (3)-C10H16)Cl-2(CNPy)] has been confirmed by single-crystal X-ray analysis. (C) 2000 .
