CdC5N2H8O5CH2 crystallizes in the orthorhombic Imm2 space group. The structure consists of four 02329_fluka molecules inside a CdC5N2H8O5 framework. In the CdC5N2H8O5 framework, Cd(1) is bonded to one N(1), one O(3), two equivalent O(1), and two equivalent O(2) atoms to form CdNO5 octahedra that share  a cornercorner with one C(1)H2N2 tetrahedra and corners with two equivalent C(2)H2N2 tetrahedra. The Cd(1)-N(1) bond length is 2.39 Å. The Cd(1)-O(3) bond length is 2.36 Å. Both Cd(1)-O(1) bond lengths are 2.32 Å. Both Cd(1)-O(2) bond lengths are 2.32 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded to two equivalent N(1) and two equivalent H(1) atoms to form CH2N2 tetrahedra that share corners with two equivalent Cd(1)NO5 octahedra and corners with four equivalent C(2)H2N2 tetrahedra. The corner-sharing octahedral tilt angles are 72°. Both C(1)-N(1) bond lengths are 1.49 Å. Both C(1)-H(1) bond lengths are 1.10 Å. In the second C site, C(2) is bonded to one N(1), one N(2), one H(2), and one H(3) atom to form CH2N2 tetrahedra that share  a cornercorner with one Cd(1)NO5 octahedra,  a cornercorner with one C(1)H2N2 tetrahedra,  a cornercorner with one C(3)H2N2 tetrahedra, and corners with two equivalent C(2)H2N2 tetrahedra. The corner-sharing octahedral tilt angles are 68°. The C(2)-N(1) bond length is 1.50 Å. The C(2)-N(2) bond length is 1.46 Å. The C(2)-H(2) bond length is 1.10 Å. The C(2)-H(3) bond length is 1.10 Å. In the third C site, C(3) is bonded to two equivalent N(2) and two equivalent H(4) atoms to form corner-sharing CH2N2 tetrahedra. Both C(3)-N(2) bond lengths are 1.48 Å. Both C(3)-H(4) bond lengths are 1.10 Å. In the fourth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(5)-O(1) bond length is 1.28 Å. The C(5)-O(2) bond length is 1.26 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cd(1), one C(1), and two equivalent C(2) atoms to form corner-sharing NCdC3 tetrahedra. In the second N site, N(2) is bonded in a trigonal non-coplanar geometry to one C(3) and two equivalent C(2) atoms. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(3) atom. In the fifth H site, H(7) is bonded in a single-bond geometry to one O(1) and one O(3) atom. The H(7)-O(1) bond length is 1.70 Å. The H(7)-O(3) bond length is 1.00 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Cd(1), one C(5), and one H(7) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one C(5) atom. In the third O site, O(3) is bonded in a water-like geometry to one Cd(1) and two equivalent H(7) atoms. Linkers: 1 C1N2CN3CN1CN(C2)C3 ,2 [O]C(=O)CC([O])=O. Metal clusters: 2 [Cd]. RCSR code: hcb.
