        Abstract
        The structural, mechanical and electronic properties of LiX6(X=C,B) compounds have been investigated by using firstprinciples techniques within density functional theory. Exchange-corelation effects were considered with the generalized gradient approximation (GGA). The single crystal elastic constants were calculated and then, the mechanical stability of LiX6(X=C,B) compounds were studied. Applying hydrostatic pressure up to 30 GPa, behaviours of them were observed under pressure. The obtaining results were compared to available data..
