Two organometallic ligands, cinnamaldehyde ferrocenecarbonylhydrazone (HL^1) and bis[(1-cinnamoylhydrazonoethyl) cyclopentadienyl] iron (H~2L^2) have been prepared. Some of transition metal complexes: ML~2^1[M=Cu(II)], ML^2[M=Cu(II) and Zn(II) ], M(HL^1)~2Cl~2[M=Cd(II), Co(II) and Ni(II)], M(H~2L^2)Cl~2[M=Mn(II), Zn(II), Co(II), and Cd(II)] were obtained by the reaction of HL^1 and H~2L^2 with relevant metal(II) acetates and chlorides, respectively. These ligands coordinate in the enolic form with M(OAc)~2.nH~2O and in the keto form with MCl~2.nH~2O.
