Abstract     Some new organic derivatives of heterocyclic β-diketone [4-chlorobenzoyl-​3-​methyl-​1-​phenyl-​2-​pyrazolin-​5-​one (CMPPOH)] of the type Ga(OPrⁱ)_3-n (CMPPO)_n (where n=1,2and 3) have been synthesized by the reactions of Ga(OPrⁱ)​₃ and heterocyclic β-diketone in different molar ratios. These derivatives were characterized by elemental analyses, mol. wt. measurements and their probable structures have been proposed on the basis of IR and ¹H NMR spectral studies.

Keywords- Elemental analyses, spectral studies, sterically hindered heterocyclic β-diketones
