The orthorhombic crystal structures of the series of Ln{sub 4-x}In{sub 5-y}S{sub 13} (Ln=La, Ce, Pr and Nd; x=0.08-0.12, y=0.21-0.24) compounds were investigated by means of X-ray crystal diffraction. The crystals of La{sub 3}In{sub 1.67}S{sub 7} and Gd{sub 3}InS{sub 6} were also obtained unexpectedly from the La-In-S and Gd-In-S systems and no respective Gd{sub 4-x}In{sub 5-y}S{sub 13} was obtained. In the structures of the orthorhombic Ln{sub 4-x}In{sub 5-y}S{sub 13} series and hexagonal La{sub 3}In{sub 1.67}S{sub 7} indium atoms occupy disordered positions in the octahedral and trigonal antiprismatic arrangement of the sulphur atoms. The crystal structure of the La{sub 4}Ag{sub 2}In{sub 4}S{sub 13} is also given and discussed as an example of quaternary sulphide related to a ternary La-In sulphide. - Graphical abstract: In the series of the Ln{sub 4-x}In{sub 5-y}S{sub 13} (Ln=La, Ce, Pr and Nd; x=0.08-0.12, y=0.21-0.24) compounds the indium atoms occupy disordered position in the octahedral arrangement of the sulphur atoms. The tetrahedral position is ordered.
