Synthesis and crystal structure of silicon pernitride SiN2 at 140 GPa
Abstract
<jats:p>Silicon pernitride, SiN<jats:sub>2</jats:sub>, was synthesized from the elements at 140 GPa in a laser-heated diamond anvil cell. Its crystal structure was solved and refined by means of synchrotron-based single-crystal X-ray diffraction data. The title compound crystallizes in the pyrite structure type (space group <jats:italic>Pa</jats:italic>{3}, No. 205). The Si atom occupies a site with multiplicity 4 (Wyckoff letter <jats:italic>b</jats:italic>, site symmetry .{3}.), while the N atom is located on a site with multiplicity 8 (Wyckoff letter <jats:italic>c</jats:italic>, site symmetry .3.). The crystal structure of SiN<jats:sub>2</jats:sub> is comprised of slightly distorted [SiN<jats:sub>6</jats:sub>] octahedra interconnected with each other by sharing vertices. Crystal chemical analysis of bond lengths suggests that Si has a formal oxidation state of +IV, while nitrogen forms pernitride anions (N—N)<jats:sup>4–</jats:sup>.</jats:p>
