STUDIES SOME COORDINATION-COMPLEXES OF BIS(CYCLOPENTADIENYL)TITANIUM(IV) DICHLORIDE AND BIS(CYCLOPENTADIENYL)ZIRCONIUM(IV) DICHLORIDE

Bis(cyclopentadienyl)titanium(IV) dichloride and bis(cyclopentadienyl) zirconium(IV) dichloride, when treated with the Schiff bases derived f rom the condensation of salicyldehyde with o-aminophenol or o-aminothi ophenol in a nonaqueous medium, form ionic complexes of the type [Cp(2 )M(L)]Cl-2, where Cp = eta(5)-C5H5, M = Ti or Zr, L = salicyclidene-o- aminophenol (L'), salicylidene-o-aminothiophenol (L ''). The secondary ligand reactions on these complexes resulted in a series;of-new compl exes. In all these. reactions the metal-ring bonds do not cleave, All the complexes-have been assigned square -pyramidal geometries.
