Synthesis, characterization and crystal structures of cyclometallated Ru(II) carbonyl complexes formed by hydrazones

Cyclometallated Ru(II) complexes of the type [Ru(CO)(EPh3)2(L)] (E = P or As; L = tridentate hydrazone-derived ligand) have been obtained by refluxing an ethanolic solution of [RuHCl(CO)(PPh3)3] or [RuHCl(CO)(AsPh3)3] with the hydrazone derivatives H2php (2-[(2,4-dinitro-phenyl)-hydrazonomethyl]-phenol), H2phm (2-[(2,4-dinitro-phenyl)-hydrazonomethyl]-6-methoxy-phenol) and H2phn (2-[(2,4-dinitro-phenyl)-hydrazonomethyl]-naphthalen-1-ol). The formation of stable cyclometallated complexes has been authenticated by single crystal X-ray structure determination of two of the complexes, and the mechanism of C-H activation is discussed in detail. The spectral (IR, UV-Vis and 1H NMR) and electrochemical data for all the complexes are reported. Electrochemistry shows a substantial variation in the metal redox potentials with regard to the electronic nature of the substituents present in the hydrazone derivative.
