Materials Data on CaH16C4(NO)10 by Materials Project

Abstract

CaC4H16(NO)10 is Protactinium structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two CaC4H16(NO)10 clusters. Ca2+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.32 Å) and two longer (2.37 Å) Ca–O bond lengths. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to two N+1.40- and one O2- atom. Both C–N bond lengths are 1.35 Å. The C–O bond length is 1.27 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to two N+1.40- and one O2- atom. Both C–N bond lengths are 1.35 Å. The C–O bond length is 1.28 Å. There are five inequivalent N+1.40- sites. In the first N+1.40- site, N+1.40- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the second N+1.40- site, N+1.40- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.01 Å. In the third N+1.40- site, N+1.40- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the fourth N+1.40- site, N+1.40- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the fifth N+1.40- site, N+1.40- is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.25–1.29 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.40- atom. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one N+1.40- atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+1.40- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one N+1.40- atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one C4+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ca2+ and one C4+ atom.
