Exploratory studies have been conducted on
the synthesis and characterization of multinary nitrides and chalcogenides.
This talk will illustrate synthetic studies aiming at finding new solid state
compounds with interesting properties. Metallic alloy (Na/Sn or Na/Ga) and alkali
metal halide flux (RbCl) were utilized for nitrides and for chalcogenides, respectively,
as a synthetic tool. Several new and by-products have been synthesized and characterized
using various techniques. Here the crystal structures and properties of two
novel nitrides (Na3Sn8N and RbSe2N2) and two thiospinel (CuZr1.86S4 and Cu0.36Hf2S4)
will be discussed.
