The isothermal
sections of the quasi-ternary NiX–La2X3–Ga(In)2X3 (X = S, Se) systems at 770 K were constructed using X-ray
diffraction. The crystal structure of the quaternary compound La3NiGaS7
(structure type La3MnGaS7, Pearson symbol hP24,
space group P63, a = 1.01605(4), c = 0.60397(3) nm, RI
= 0.0856, Rp
= 0.1897) was determined by X-ray powder diffraction.
Unit cell and coordination polyhedra of the atoms in the La3NiGaS7
structure.
