摘要：

The novel isotypic hexagonal alkaline earth metal nitride chalcogenides Ca6N2Se3, Sr6N2Se3 and Sr6N2Te3 (R 3c (No.167); Z=6) were synthesized from Ca(Sr)/Na flux at 1173 K. The compounds belong to the rare class of ternary metal nitride chalcogenides. The structures feature the shortest Ca/Sr-N bonds within the regular trigonal antiprismatic coordination (Ca-N: 235.17(8); Sr-N: 251.20(6) pm). Two crystallographic distinct nitrogen atoms are coordinated in a trigonal antiprism and a twisted trigonal prism, respectively, and are alternatively condensed via trigonal trans-faces to form one-dimensional chains infinity 1NAE6/2f3+. The chalcogenide ions in comparison realize rather ambiguous environments. Raman spectroscopic data are reported.
