Abstract
Zirconium(IV) Schiff base chelates having the general formula ZrL(OPr
i
)2 [where LH

i
)4.Pr
i
OH with sterically constrained sulfur-containing Schiff bases of heterocyclic β -diketones in a 1:1 molar ratio in dry refluxing benzene. The complexes ZrL(OPr
i
)

were used as important precursors for the synthesis of the complexes of the type Zr(L)
2
. The complexes, Zr(L)

, were prepared by the interaction of precursor ZrL(OPr
i
)
2
with sterically constrained sulfur-containing Schiff bases of heterocyclic β -diketones in a 1:1 molar ratio in dry benzene. The structures of these zirconium(IV) chelates have been discerned with the help of elemental analyses, physicochemical studies, and spectral [IR and NMR (
1
H and
13
C)] data. A distorted trigonal bipyramidal and a distorted octahedral geometry may be assigned to zirconium(IV) chelates of the types ZrL(OPr
i
)
2
and Zr(L)

, respectively.
