The full potential-linearized augmented plane wave method has been used to calculate structural, electronic and transport properties of proposed -22-compounds namely SrNi2Bi2 and BaNi2Bi2 using first principle calculations. These compounds belong to ThCr2Si2-type tetragonal structure and are isostructural with SrNi2(P/As)2 and BaNi2(P/As)2 compounds. The lattice constants of SrNi2Bi2 and BaNi2Bi2 are derived from their respective parent compounds. Optimized lattice constant, energy band structure, electron density plots and superconducting transition temperature are computed for the parent compounds. The calculated results are in reasonable agreement with earlier experimental values and theoretical results. The proposed compounds show similar electronic and bonding characteristics of their respective parent low temperature superconductors.
