Abstract

Metal complexes of Schiff bases represent an important class of coordination compounds. Bis(cyclopentadienyl)titanium(IV) and zirconium(IV) chlorides react with bis(hydrazones) derived from 1,1'- diacetylruthenocene in anhydrous THF in the presence of base to give complexes of the type [(Cp2MCl)2L] [M=Ti or Zr; LH2 = ruthenocenyl bis(hydrazones)]. Tentative structures are proposed for these complexes based upon elemental analyses, electrical conductance, magnetic moment and spectroscopic data.
