ABSTRACT
Na 3 InP 2 ternary compound, which crystallizes in the monoclinic structure with the lattice parameters a = 940.1 ± 0.5, b = 737.1 ± 0.4, and c = 1535.8 ± 0.4 pm and β = 92.4 ± 0.1°, is formed in the In–Na–P system (Blase et al. 1991h). It was prepared from the elements at 600°C in sealed Nb ampoules.
