Abstract
Phenylphosphinic acid (HPhPO2H) and phenylphosphonic acid (PhPO3H2) react with a methanolic solution of [Rui(µ-O2CCH3MO2CCH3h]H · 0.7H2O at room temperature to give [Rui(µ-O2CCH3MHPhPO2) 2]H (1) and [Ruiµ-O2CCH3)4 (PhPO3H)2]H · H2O (2), respectively. The X-ray crystal structures of 1 and 2 each show the Ru-Ru core to be ligated by four bridging bidentate acetate ligands [Ru-Ru distances: 1 = 2.272( I) A; 2 = 2.267(2) A.) and two axial phenylphosphinate and phenylphosphonate ligands, respectively. In each complex the individual bimetallic molecules are linked together by a hydrogen ion which bridges the oxygen atoms of neighbouring axial ligands. In 2 the water molecule is also hydrogen-bonded to one of the axial phenylphosphonate groups. Spectroscopic, magnetic and cyclic voltammetric data for the complexes are given.
