The formation of the title compounds by reaction of copper with yellow ammonium sulphide solutions is investigated. The new compound NIf,Cu,S, is isotypic to KCu,S, (space group P4/mmm, a = 3.907 A, c = 9.453 A) The topotactic decomposition of NI-I,Cu,S, to digenite between 120-140°C is studied and
Ammonium chloride/mercuric chloride mixtures (molar ratio 2:1) react at 3503 3C with Monel (Cu68Ni32) to yield (NH 4 )NiCl 3 and mercury and copper amalgam, respectively. With larger amounts of (NH 4 )Cl in the reaction mixture, dark green is also formed as a main product. Light blue crystals of th
An embedded cluster model, including both the electrostatic potential of the infinite crystal and electron correlation, is used to predict the adsorption energies of NH 3 and NH~-in zeolites. The importance of both effects is shown by comparison of the calculated difference of the zeolite proton aff
