Abstract
Five new equiatomic lanthanoid-cadmium oxide pnictides LnOCdPn (Ln = rare-earth, Pn = pnictogen) have been prepared. All of them crystallize in the tetragonal LaOAgS structure type. The phosphide series is represented by La compound only; arsenides were found for Ln = La-Nd. The structure of CeOCdAs (P4/nmm, a = 4.1852(1)Angstrom, c = 9.1595(3)Angstrom, R-p = 0.054, R-wp = 0.071) has been solved from X-ray powder data. Similarities between structures of CeOCdAs, isoelectronic CeOZnSb, and related LaOCd0.5Se are discussed. (C) 1999 Published by Elsevier Science S.A. All rights reserved.
