Synthesis of mono-crystalline Ga
2O
3 Nanorods was done by sol-gel transformation of gallium(III) isopropoxide (Ga(OPr
i)
3). XRD studies were done to determine the planes and crystal structure of synthesized nanorods that showed the synthesis of β-Ga
2O
3(a). TEM studies of synthesized Ga
2O
3 confirmed the synthesis of monocrystalline β-Ga
2O
3 nanorods. To study the effect of precursor chemistry and to determine role of precursor structures on the crystal structure, phase and morphology of the Ga
2O
3, a new modified precursor complex was synthesized. The reaction of Ga(OPr

1H and
13C) spectral studies. Spectral studies of the modified complex suggest the presence of bi-dentate mode of attachment of Schiff's base in the solution state. Sol-gel transformations of [{(H

b), as found by XRD studies. TEM image of the sample (
a) revealed the formation of nano-rods of oxide with average diameter of ~100?nm whereas the TEM image of sample (
b) showed presence of nano-sized particles of oxide with average particle size of 10?nm. Morphological and compositional studies of synthesized samples
(a) and
(b) were carried out using SEM and EDX. The method provides a possibility of large scale synthesis of dissimilar shaped and pure Ga
