New mixed alkaline-earth nitridomolybdate(vi) nitride oxides with anion-ordered sub-structures†
Abstract
New molybdenum(VI) nitride
(no. 2). The mixed alkaline earth compounds with composition Ca38Sr13[MoN4]12N8O3 and Ca36Sr15[MoN4]12N8O3 are isostructural with the quaternary nitride oxides Sr51[WN4]12N8O3 and Ca51[WN4]12N8O3. The structures contain isolated [MoN4]6− tetrahedra, partially disordered
