Synthesis and Structure of the New Ternary Nitride SrTiN(2).

A new ternary nitride, SrTiN(2), has been synthesized by the solid-state reaction of Sr(2)N with TiN and characterized by powder X-ray diffraction. SrTiN(2) crystallizes in the tetragonal space group P4/nmm (a = 3.8799(2) Å, c = 7.6985(4) Å, Z = 2) and is isostructural with KCoO(2). Titanium is coor...

Summary:A new ternary nitride, SrTiN(2), has been synthesized by the solid-state reaction of Sr(2)N with TiN and characterized by powder X-ray diffraction. SrTiN(2) crystallizes in the tetragonal space group P4/nmm (a = 3.8799(2) Å, c = 7.6985(4) Å, Z = 2) and is isostructural with KCoO(2). Titanium is coordinated to five nitrogens in a distorted square-based pyramidal geometry, forming layers of edge-sharing pyramids which stack along the (001) direction. Strontium is situated between the Ti-N layers and is coordinated to five nitrogen atoms. The title compound is only the third example of a ternary titanium nitride.
