A series of polycrystalline bulk samples Mg1.2C1.6-xBxNi3 (x = 0.0, 0.08 and 0.16) is synthesized through standard solid-state reaction route, which are found to crystallize in cubic perovskite structure with space group Pm3m. Rietveld analysis of observed XRD data show that lattice parameters expand from a = 3.8106 (4) {\\AA} for pure, to 3.8164 (2) {\\AA} and 3.8173 (5) {\\AA} for 5% and 10% Boron substituted samples respectively.
