Mn_1.5AgIn_8.0S₁₄ single crystals were grown by Bridgman directed melt crystallization. Their composition and crystal structure were determined. Single crystals crystallized in the cubic spinel structure with lattice constant a = 10.765 ± 0.005 Å. The band-gap width of Mn_1.5AgIn_8.0S₁₄ single crystals was estimated from transmission spectra near the intrinsic absorption edge in the temperature range 10–320 K and decreased with increasing temperature. A function approximating this dependence was obtained.
