Alkaline-earth rich (Ca,Th)(N,O) and (Sr,Th)(N,O) can be prepared from
reactions of the binary nitrides at 1000 degrees C. Th2N2O impurities
in the starting material, Th3N4, resulted in oxygen incorporation in
the final compound. The black products crystallize in the rocksalt str
ucture type in which the cations are disordered (a = 5.101(5) Angstrom
and a = 5.241(2) Angstrom, respectively). They exhibit semiconducting
behavior. (C) 1995 Academic Press, Inc.
