Theoretical prediction of the structural, elastic, electronic and thermodynamic properties of V3M (MÂ =Â Si, Ge and Sn) compounds

► V3Sn compound is mechanically unstable. ► The lowest energy structure is found to have the lowest N(Ef) value. ► The interaction between M (M = Si, Ge, Sn) and V [M and M] is negative, not including Si [Sn].
