Materials Data on Dy(NO3)3 by Materials Project
Dy(NO3)3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Dy(NO3)3 sheet oriented in the (0, 0, 1) direction. Dy3+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Dy–O bond distances ranging from 2.37–2.73 Å. There are three inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.25–1.28 Å. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.26 Å) and one longer (1.27 Å) N–O bond length. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.31 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Dy3+ and one N5+ atom. In the second O2- site, O2- is bonded in a distorted L-shaped geometry to one Dy3+ and one N5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Dy3+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Dy3+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a distorted L-shaped geometry to one Dy3+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Dy3+ and one N5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Dy3+ and one N5+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one Dy3+ and one N5+ atom. In the ninth O2- site, O2- is bonded in a distorted L-shaped geometry to one Dy3+ and one N5+ atom.
