Density functional theory B3LYP method with relativistic effective core potential and SDD basis for La and Ni atom has been used to optimize the structure and to calculate inter energy E,entropy S of LaH2 and NiH2 molecule.

In the present paper, firstly, the electronic state and reasonable dissociation limits of NiH 2 are correctly determined based on group theory and atomic and molecular reaction statics.
