We predict that V2Ga2C is thermodynamically stable with respect to all identified competing phases in the ternary V-Ga-C phase diagram.  We further calculate the stability of ordered and disordered configurations of Mo and V in (Mo1-xVx)2Ga2C and predict that ordered (Mo1-xVx)2Ga2C for x≤ 0.25 is stable, with an order-disorder transition temperature of ∼1000 K. Furthermore, (Mo1-xVx)2Ga2C for x = 0.5 and x≥ 0.75 is suggested to be stable, but only for disordered Mo-V configurations, and only at elevated temperatures.
