Abstract
The validity of the recently enunciated average-entropy equation, using symmetry-corrected absolute entropies, was tested against the values obtained from the literature and from accurate quantum chemical calculations. We analyze this validity for the series of yet unexplored alkali metal borides MeB (Me = Li, Na, K, Rb, Cs).
