Materials Data on YSe2NO11 by Materials Project

Abstract

YNSe2O11 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is two-dimensional and consists of two YNSe2O11 sheets oriented in the (0, 0, 1) direction. Y is bonded in a 6-coordinate geometry to eight O atoms. There are a spread of Y–O bond distances ranging from 2.30–2.67 Å. N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.24–1.27 Å. There are two inequivalent Se sites. In the first Se site, Se is bonded in a trigonal non-coplanar geometry to three O atoms. There is two shorter (1.70 Å) and one longer (1.85 Å) Se–O bond length. In the second Se site, Se is bonded in a trigonal non-coplanar geometry to three O atoms. There are a spread of Se–O bond distances ranging from 1.69–1.85 Å. There are eleven inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Y and one Se atom. In the second O site, O is bonded in a single-bond geometry to one Y atom. In the third O site, O is bonded in a single-bond geometry to one Y atom. In the fourth O site, O is bonded in a single-bond geometry to one Y atom. In the fifth O site, O is bonded in a distorted bent 120 degrees geometry to one Y and one Se atom. In the sixth O site, O is bonded in a single-bond geometry to one N atom. In the seventh O site, O is bonded in a bent 120 degrees geometry to one Y and one Se atom. In the eighth O site, O is bonded in a distorted single-bond geometry to one Y and one N atom. In the ninth O site, O is bonded in a bent 120 degrees geometry to two Se atoms. In the tenth O site, O is bonded in a single-bond geometry to one N atom. In the eleventh O site, O is bonded in a bent 120 degrees geometry to one Y and one Se atom.
