Zn2H3(C3O2)3 crystallizes in the cubic P2_13 space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. All Zn(1)-O(1) bond lengths are 1.92 Å. In the second Zn site, Zn(2) is bonded in a distorted T-shaped geometry to three equivalent O(2) atoms. All Zn(2)-O(2) bond lengths are 2.06 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(2) atoms. The C(1)-C(3) bond length is 1.51 Å. There is one shorter (1.36 Å) and one longer (1.43 Å) C(1)-C(2) bond length. In the second C site, C(2) is bonded in a distorted single-bond geometry to two equivalent C(1) and one H(1) atom. The C(2)-H(1) bond length is 0.93 Å. In the third C site, C(3) is bonded in a bent 120 degrees geometry to one C(1), one O(1), and one O(2) atom. The C(3)-O(1) bond length is 1.28 Å. The C(3)-O(2) bond length is 1.21 Å. H(1) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one C(3) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Zn(2) and one C(3) atom. Linkers: 4 [O]C(=O)c1cc(C([O])=O)cc(C([O])=O)c1.
