Na3(AlSi)Te4 has been prepared and analytically characterized. The compound is monoclinic, C2/m, with a = 747 ± 1 pm, b = 434 ± 1 pm, c = 852 ± 1 pm, β = 107.4° ±0.1. The structure can be described as a variant of the a-NaFeO2-type. One half of the octahedral sites is occupied by Na ions while in the other half of these holes Na ions and Al-Si-dumbbells in the ratio 1:1 are randomly distributed.
