ZnH4(C3O)4(CH)4 crystallizes in the orthorhombic Pnma space group. The structure consists of sixteen 02329_fluka molecules inside a ZnH4(C3O)4 framework. In the ZnH4(C3O)4 framework, Zn(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Zn(1)-O(1) bond lengths are 2.04 Å. Both Zn(1)-O(2) bond lengths are 2.06 Å. There are six inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(7) atom. The C(2)-C(1) bond length is 1.40 Å. The C(2)-C(3) bond length is 1.43 Å. The C(2)-C(7) bond length is 1.44 Å. In the second C site, C(1) is bonded in a trigonal planar geometry to one C(2), one C(7), and one C(8) atom. The C(1)-C(7) bond length is 1.40 Å. The C(1)-C(8) bond length is 1.52 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.94 Å. In the fourth C site, C(6) is bonded in a distorted single-bond geometry to one C(7) and one H(4) atom. The C(6)-C(7) bond length is 1.43 Å. The C(6)-H(4) bond length is 0.94 Å. In the fifth C site, C(7) is bonded in a trigonal planar geometry to one C(1), one C(2), and one C(6) atom. In the sixth C site, C(8) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(1), and one O(2) atom. The C(8)-O(1) bond length is 1.25 Å. The C(8)-O(2) bond length is 1.25 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(6) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one C(8) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Zn(1) and one C(8) atom. Linkers: 6 [O]C(=O)c1c2ccccc2c(C([O])=O)c2ccccc12. Metal clusters: 4 [Zn].
