Ammonium hexachlorostannate single crystals were obtained from gas phase of decomposition products of SnCl4·5NH3 formed in reaction of liquid tin(IV) chloride with gaseous ammonia. The crystals of both cubic (NH4)2SnCl6, obtained hitherto only by cr

Mixtures of powders of gallium nitride and manganese were annealed in a stream of ammonia at temperatures from the range of 1200–1250°C. The procedure resulted in preparation of bulk single crystals of gallium nitride of dimensions up to 2.7×1.5
