YCl6YC18H48(N2O)6 is Tungsten structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of three YC18H48(N2O)6 clusters and three YCl6 clusters. In each YC18H48(N2O)6 cluster, Y3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Y–O bond lengths are 2.25 Å. There are three inequivalent C sites. In the first C site, C is bonded in a tetrahedral geometry to one N3- and three H1+ atoms. The C–N bond length is 1.45 Å. All C–H bond lengths are 1.10 Å. In the second C site, C is bonded in a tetrahedral geometry to one N3- and three H1+ atoms. The C–N bond length is 1.45 Å. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. In the third C site, C is bonded in a trigonal planar geometry to two N3- and one O2- atom. Both C–N bond lengths are 1.35 Å. The C–O bond length is 1.28 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to two C and one H1+ atom. The N–H bond length is 1.03 Å. In the second N3- site, N3- is bonded in a trigonal planar geometry to two C and one H1+ atom. The N–H bond length is 1.02 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one C atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one C atom. O2- is bonded in a linear geometry to one Y3+ and one C atom. In each YCl6 cluster, Y3+ is bonded in an octahedral geometry to six equivalent Cl1- atoms. All Y–Cl bond lengths are 2.66 Å. Cl1- is bonded in a single-bond geometry to one Y3+ atom.
