During reinvestigation of the hydrothermal synthesis reported earlier of the compound cesium nickel phosphide, 'CsNiP', we arrived at a new route to the synthesis of the cesium nickel halide compounds CsNiX{sub 3} (X=Cl, Br, I). The method has also been shown to extend to cobalt and iron compounds. Single crystals of these compounds were synthesized in phosphoric acid in sealed autoclaves. Their structures were determined by single-crystal X-ray diffraction methods. The compounds crystallize in the hexagonal space group P6{sub 3}/mmc in the BaNiO{sub 3} structure type. The synthetic method and the resultant crystallographic details for CsNiCl{sub 3} are essentially identical with those reported earlier for the synthesis and structure of 'CsNiP'. - Graphical abstract: The CsNiX{sub 3} (X=Cl, Br, I) structure. Cesium is blue, nickel is in dark green polyhedra, halide is brown. Highlights: Black-Right-Pointing-Pointer A hydrothermal approach to single crystal growth of cesium transition-metal halides.
