Synthesis, Structure, and Properties of a New Intermetallic Compound, Ca7Ni4Sn13.

摘要

We have previously reported that ternary metal nitrides of the general composition CaxMyNz, where M is a transition metal or post transition metal, are readily prepared as polycrystalline powders by reaction of Ca3N2 and M under N2 at temperatures on the order of 100 C. When the structures are relatively simple, we have been able to determine the structures by x-ray or neutron powder diffraction. In only a few instances have we obtained single crystals. In order to prepare single crystals of materials with more complicated structures, we have been attempting to develop general methods of nitride crystal growth using molten salts or metal fluxes.
