Abstract
Slow evaporation method was usedto develop the metal organic compound of potassium hydrogen oxalatehydrate. The
crystal system and lattice constant of the developed compound were analyzed with the help of singlecrystal X-ray
diffractiontechnique. For diverse temperature,the nucleation curve and solubility of the compound werecalculated
experimentally. The solubility curve showed that the compound exhibit a positive temperature gradient of solubility.
Various parameters for growth kinetics such asfree energy change, induction period, nucleation rate wereevaluated
experimentally. The semiconductor laser of wavelength 532 nm was utilizedin the Z-scanmethod to determinedifferent
nonlinear parameters likethird-order refractive index, susceptibility and absorption coefficient.
