Abstract

The ruthenium complexes trans, trans, trans-{[}RuCl2(POMe-P)(2)(FcC(6)H(4)NC)(2)] (1) (POMe = PPh2C6H4OCH3; Fc = ferrocenyl) and trans, trans, trans -{[}RuCl2(PC2OMe-P)(2)(FCC6H4NC)(2)] (2) (PC2OMe = PPh2CH2CH2OCH3) have been prepared by reaction of FcC(6)H(4)NC with {[}RuCl2(POMe-P,O)(2)] (5) and {[}RuCl2(PC2OMe-P,O)(2)] (6), respectively. The mixed carbonyl-isocyanide complexes trans, trans, trans -{[}RuCl2(PoMe-P)(2)(Co)(FcC(6)H(4)NC)] (3) and trans, trans, trans -{[}RuCl2(PC2OMe-P)(2)- (CO)(FcC(6)H(4)NC)] (4) were prepared by sequential reaction of 5 and 6 with carbon monoxide and FcC(6)H(4)NC, respectively. These complexes have all been characterized by H-1-NMR, P-31-NMR and infrared spectroscopies as well as microanalysis. The solid-state structure of 1 was determined by X-ray crystallography. All three pairs of ligands are trans in this complex, and the ferrocenyl groups are tilted with respect to the phenyl ring plane by 28 degrees. Cyclic voltammetry of these complexes reveals essentially no electronic interaction occurs between the ferrocenyl groups and the Ru. (C) 2001 Elsevier Science B.V. All rights reserved.
