Cu2C29H16O8 crystallizes in the tetragonal P4_2/mmc space group. Cu(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. All Cu(1)-O(1) bond lengths are 1.95 Å. There are six inequivalent C sites. In the first C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(5), and one H(2) atom. The C(2)-C(1) bond length is 1.37 Å. The C(2)-C(5) bond length is 1.38 Å. The C(2)-H(2) bond length is 0.93 Å. In the second C site, C(1) is bonded in a distorted single-bond geometry to one C(2), one C(3), and one H(1) atom. The C(1)-C(3) bond length is 1.37 Å. The C(1)-H(1) bond length is 0.93 Å. In the third C site, C(3) is bonded in a trigonal planar geometry to one C(6) and two equivalent C(1) atoms. The C(3)-C(6) bond length is 1.56 Å. In the fourth C site, C(4) is bonded in a distorted bent 120 degrees geometry to one C(5) and two equivalent O(1) atoms. The C(4)-C(5) bond length is 1.55 Å. Both C(4)-O(1) bond lengths are 1.26 Å. In the fifth C site, C(5) is bonded in a trigonal planar geometry to one C(4) and two equivalent C(2) atoms. In the sixth C site, C(6) is bonded in a tetrahedral geometry to four equivalent C(3) atoms. There are two 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. O(1) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one C(4) atom. Linkers: 2 [O]C(=O)c1ccc(C(c2ccc(C([O])=O)cc2)(c2ccc(C([O])=O)cc2)c2ccc(C([O])=O)cc2)cc1.
