NdC3H4O8(CH2)2 crystallizes in the orthorhombic Fddd space group. The structure consists of thirty-two 02329_fluka molecules inside a NdC3H4O8 framework. In the NdC3H4O8 framework, Nd(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. Both Nd(1)-O(1) bond lengths are 2.57 Å. Both Nd(1)-O(2) bond lengths are 2.41 Å. Both Nd(1)-O(3) bond lengths are 2.52 Å. Both Nd(1)-O(4) bond lengths are 2.59 Å. There are two inequivalent C sites. In the first C site, C(3) is bonded in a distorted bent 120 degrees geometry to two equivalent O(3) atoms. Both C(3)-O(3) bond lengths are 1.27 Å. In the second C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.27 Å. The C(1)-O(2) bond length is 1.28 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one O(3) and one O(4) atom. The H(1)-O(3) bond length is 1.67 Å. The H(1)-O(4) bond length is 1.00 Å. In the second H site, H(2) is bonded in a single-bond geometry to one O(4) atom. The H(2)-O(4) bond length is 0.97 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Nd(1) and one C(1) atom. In the second O site, O(4) is bonded in a water-like geometry to one Nd(1), one H(1), and one H(2) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to one Nd(1) and one C(1) atom. In the fourth O site, O(3) is bonded in a distorted trigonal planar geometry to one Nd(1), one C(3), and one H(1) atom. Linkers: 4 [O]C(=O)CCC([O])=O ,2 [O]C(=O)C([O])=O. Metal clusters: 4 [Nd].
