Na12Ni2C27H9(N3O10)2(CH)3 crystallizes in the hexagonal P6_3/m space group. The structure consists of six 02329_fluka molecules inside a Na12Ni2C27H9(N3O10)2 framework. In the Na12Ni2C27H9(N3O10)2 framework, there are two inequivalent Na sites. In the first Na site, Na(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form distorted NaO5 square pyramids that share  an edgeedge with one Ni(1)N3O3 octahedra and edges with two equivalent Na(1)O5 square pyramids. The Na(1)-O(2) bond length is 2.33 Å. The Na(1)-O(3) bond length is 2.30 Å. The Na(1)-O(4) bond length is 2.61 Å. There is one shorter (2.30 Å) and one longer (2.70 Å) Na(1)-O(1) bond length. In the second Na site, Na(2) is bonded in a single-bond geometry to one O(2) atom. The Na(2)-O(2) bond length is 2.51 Å. Ni(1) is bonded to three equivalent N(1) and three equivalent O(1) atoms to form NiN3O3 octahedra that share edges with three equivalent Na(1)O5 square pyramids. All Ni(1)-N(1) bond lengths are 2.06 Å. All Ni(1)-O(1) bond lengths are 2.10 Å. There are five inequivalent C sites. In the first C site, C(5) is bonded in a distorted single-bond geometry to two equivalent C(3) and one H(2) atom. Both C(5)-C(3) bond lengths are 1.38 Å. The C(5)-H(2) bond length is 0.93 Å. In the second C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.26 Å. The C(1)-O(2) bond length is 1.23 Å. In the third C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one O(3) atom. The C(2)-N(1) bond length is 1.28 Å. The C(2)-O(3) bond length is 1.28 Å. In the fourth C site, C(3) is bonded in a distorted trigonal planar geometry to one C(4), one C(5), and one N(1) atom. The C(3)-C(4) bond length is 1.37 Å. The C(3)-N(1) bond length is 1.43 Å. In the fifth C site, C(4) is bonded in a distorted single-bond geometry to one C(3) and one H(1) atom. The C(4)-H(1) bond length is 0.93 Å. N(1) is bonded in a trigonal planar geometry to one Ni(1), one C(2), and one C(3) atom. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(5) atom. In the second H site, H(1) is bonded in a single-bond geometry to one C(4) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted T-shaped geometry to three equivalent Na(1) atoms. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Ni(1), and one C(1) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to one Na(1), one Na(2), and one C(1) atom. In the fourth O site, O(3) is bonded in a bent 120 degrees geometry to one Na(1) and one C(2) atom. Linkers: 6 [O]C(=O)C(=O)[N]c1cccc([N]C(=O)C([O])=O)c1. Metal clusters: 24 [Na] ,4 [Ni].
