The structure described by YbC5H9(NO4)2 crystallizes in the monoclinic C2 space group. Yb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one N(1), one H(3), and one O(2) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one H(4), one O(3), and one O(4) atom. In the third C site, C(3) is bonded in a trigonal planar geometry to one H(5) and two equivalent O(1) atoms. N(1) is bonded in a trigonal planar geometry to one C(1), one H(1), and one H(2) atom. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Yb(1) and one C(3) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Yb(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Yb(1) and one C(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Yb(1) and one C(2) atom. is represented by the CIF file [CIF]
