Materials Data on YNO4 by Materials Project
YONO3 crystallizes in the orthorhombic Aem2 space group. The structure is two-dimensional and consists of one YONO3 sheet oriented in the (0, 0, 1) direction. Y3+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.24–2.61 Å. N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.21 Å) and two longer (1.31 Å) N–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Y3+ atoms to form a mixture of corner and edge-sharing OY4 tetrahedra. In the second O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Y3+ and one N5+ atom.
