Abstract: Na<sub>2</sub>NiP<sub>2</sub>O<sub>7</sub> crystals were synthesized by soft hydrothermal rout at moderate pressure-temperature conditions. Highest degree of crystallinity observed at critical concentration of initial components and beyond which the crystallinity collapse sharply to minimum. Solubility studies revealed positive thermal coefficient with relatively high enthalpy in H<sub>3</sub>PO<sub>4</sub>. Magnetic results indicated that it is a frequency dependent paramagnetic material.
