AbstractThe salt [RuCl2(CO)2ln has proved very useful precursor for the syntheses of a variety of organometallic complexes of transition metals. The compounds of dichlorodicarbonylruthenium(II) of the formula [RuCl2(CO)22L] or [RuCl2(CO)2L'J where L= monodentate ligands such as tetramethylthiourea or substituted ureas, naphthisoxazole, 2-aminobenzthiazole or thioacetamide and L' = bidentate ligands such as 1,2-diaminoethane, 2,2'-dipyridylamine, 1-acetylferrocenethiosemicarbazone (1-AFTSC) or 1-acetylferrocenesemicarbazone (1-AFSC) have been prepared. The versatile nature of these ligands (L or L) has shown that they react readily with [RuCl2(CO)2ln giving very stable Ru(II) complexes. For example, the complex 1-acetylferrocenethiosemicarbazone, 7i-C5H5FeC5H4.CH3C=N.NH.CS.NH2. (1-AFTSC) or 1-acetylferrocenesemicarbazone, 7i-C5H5FeC5H4CH3C=N. NH.CO.NH2- (1-AFSC) acts as bidentate ligand in which thiosemicarbazone or semicarbazone moiety acts as bridge between two metal systems giving bimetallic complexes. Thus, the reaction of [RuCl2(CO)2]n with 1-AFTSC or 1-AFSC yields 1-acetylferrocenethiosemicarbazone dichlorodicarbonylruthenium (II) [7C-C5H5FeC5H4CH3C=N. NH.CS.NH2RuCl2(CO)2] or 1-acetylferrocenesemicarbazone dichlorodicarbonylruthenium(H) [7C-C5H5FeC5H4CH3C=N.NH.CO.NH2.RuCl2(CO)2] complexes respectively as shown in the scheme of reactions (Fig. 1). Similarly reactions of CuX2(X = Cl or Br) and NiCl2.XH2O with 1-AFTSC yield respective organometallic complexes. All the complexes were identified by elemental analysis and were characterized by IR treated with [RuCl2(CO)2]n[8]. However, 1-acetylferrocenethiosemicarbazone, (7C-C5H5FeC5H4CH3 C=N.NH.CS.NH2) has proved very useful bidentate ligand. and ^H-NMR spectroscopy and elemental analyses.
