Abstract
A series of [cp2ZrL]+[RR′NCS2] complexes (where Lis the conjugate base of acetylacetone, benzoylacetone or 8-hydroxyquinoline (oxine) and R = CH3, R′ = C6H5CH2; R = C2H5, R′ = C6H4°CH3; R = H, R′ = C5H9; RR′ = C6H12) have been synthesised in aqueous medium by the reaction of [Cp2ZrL]+Cl with RR′NCS2 Na+. Conductivity measurements indicate that these complexes are 1:1 electrolytes in nitrobenzene. IR and 1H NMR spectral studies demonstrate that the ligand L is chelating in all these complexes. Consequently, tetrahedral coordination about the zireonium atom is proposed. In addition to these studies, elemental analyses and magnetic susceptibility have also been carried out for these complexes.
