NdCO4 crystallizes in the orthorhombic Pnma space group. Nd(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), and six equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Nd(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Nd(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Nd(1) and one C(1) atom.
NdCO4 crystallizes in the orthorhombic Pnma space group. Nd(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), and six equivalent O(3) atoms. There is one shorter (2.39 Å) and one longer (2.40 Å) Nd(1)-O(1) bond length. Both Nd(1)-O(2) bond lengths are 2.54 Å. There are a spread of Nd(1)-O(3) bond distances ranging from 2.61-2.75 Å. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(3) atoms. The C(1)-O(2) bond length is 1.29 Å. Both C(1)-O(3) bond lengths are 1.30 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Nd(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Nd(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Nd(1) and one C(1) atom.
