Pr2Co3C24(NO4)6(CH)18 crystallizes in the hexagonal P6cc space group. The structure consists of thirty-six 02329_fluka molecules inside a Pr2Co3C24(NO4)6 framework. In the Pr2Co3C24(NO4)6 framework, Pr(1) is bonded in a 9-coordinate geometry to three equivalent N(1), three equivalent O(1), and three equivalent O(2) atoms. All Pr(1)-N(1) bond lengths are 2.58 Å. All Pr(1)-O(1) bond lengths are 2.48 Å. All Pr(1)-O(2) bond lengths are 2.51 Å. Co(1) is bonded in a square co-planar geometry to two equivalent O(3) and two equivalent O(4) atoms. Both Co(1)-O(3) bond lengths are 2.12 Å. Both Co(1)-O(4) bond lengths are 2.03 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted single-bond geometry to one N(1) atom. The C(1)-N(1) bond length is 1.38 Å. In the second C site, C(5) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. The C(5)-O(2) bond length is 1.26 Å. The C(5)-O(3) bond length is 1.19 Å.
