Materials Data on PrNO5 by Materials Project
PrNO5 crystallizes in the monoclinic P2_1 space group. The structure is two-dimensional and consists of one PrNO5 sheet oriented in the (0, 0, 1) direction. Pr is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Pr–O bond distances ranging from 2.38–2.58 Å. N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.22–1.32 Å. There are five inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to three equivalent Pr atoms. In the second O site, O is bonded in a distorted trigonal planar geometry to three equivalent Pr atoms. In the third O site, O is bonded in a distorted single-bond geometry to two equivalent Pr and one N atom. In the fourth O site, O is bonded in a single-bond geometry to one N atom. In the fifth O site, O is bonded in a distorted water-like geometry to one Pr and one N atom.
