Materials Data on Pb3NO6 by Materials Project

Abstract

(PbO)3NO3 crystallizes in the orthorhombic Pca2_1 space group. The structure is two-dimensional and consists of four nitric acid molecules and two PbO sheets oriented in the (0, 0, 1) direction. In each PbO sheet, there are three inequivalent Pb sites. In the first Pb site, Pb is bonded in a 4-coordinate geometry to four O atoms. There are a spread of Pb–O bond distances ranging from 2.33–2.42 Å. In the second Pb site, Pb is bonded in a 4-coordinate geometry to four O atoms. There are a spread of Pb–O bond distances ranging from 2.29–2.76 Å. In the third Pb site, Pb is bonded in a 3-coordinate geometry to three O atoms. There are a spread of Pb–O bond distances ranging from 2.28–2.35 Å. There are three inequivalent O sites. In the first O site, O is bonded to four Pb atoms to form a mixture of corner and edge-sharing OPb4 tetrahedra. In the second O site, O is bonded to four Pb atoms to form a mixture of corner and edge-sharing OPb4 tetrahedra. In the third O site, O is bonded in a distorted L-shaped geometry to three Pb atoms.
