In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.30 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one C(5) and one H(2) atom. The C(2)-C(5) bond length is 1.36 Å. The C(2)-H(2) bond length is 0.93 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(7) and one H(3) atom. The C(3)-C(7) bond length is 1.34 Å. The C(3)-H(3) bond length is 0.93 Å. In the fourth C site, C(4) is bonded in a bent 120 degrees geometry to one C(5) and two equivalent O(2) atoms. The C(4)-C(5) bond length is 1.48 Å. Both C(4)-O(2) bond lengths are 1.24 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 distorted bent 120 degrees geometry to one C(7) and two equivalent O(1) atoms. The C(6)-C(7) bond length is 1.51 Å. Both C(6)-O(1) bond lengths are 1.28 Å. In the seventh C site, C(7) is bonded in a trigonal planar geometry to one C(6) and two equivalent C(3) atoms. N(1) is bonded in a trigonal planar geometry to one Co(1) and two equivalent C(1) atoms. There are three 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(3) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a trigonal planar geometry to three equivalent Co(1) atoms. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one C(6) atom. In the third O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one C(4) atom. Linkers: 6 [O]C(=O)c1ccc(C([O])=O)cc1 ,12 [O]C(=O)c1ccncc1.
