PrC5NHO4(CH)2 crystallizes in the tetragonal I4_1/a space group. The structure consists of thirty-two 02329_fluka molecules inside a PrC5NHO4 framework. In the PrC5NHO4 framework, Pr(1) is bonded in a 5-coordinate geometry to one N(1), one O(1), one O(2), one O(3), and one O(4) atom. The Pr(1)-N(1) bond length is 2.61 Å. The Pr(1)-O(1) bond length is 2.50 Å. The Pr(1)-O(2) bond length is 2.48 Å. The Pr(1)-O(3) bond length is 2.48 Å. The Pr(1)-O(4) bond length is 2.51 Å. There are five 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 1.32 Å. In the second C site, C(4) is bonded in a distorted single-bond geometry to one C(5) and one H(3) atom. The C(4)-C(5) bond length is 1.37 Å. The C(4)-H(3) bond length is 0.93 Å. In the third C site, C(5) is bonded in a distorted trigonal planar geometry to one C(4), one C(6), and one N(1) atom. The C(5)-C(6) bond length is 1.50 Å. The C(5)-N(1) bond length is 1.34 Å. In the fourth C site, C(6) is bonded in a distorted bent 120 degrees geometry to one C(5), one O(1), and one O(4) atom. The C(6)-O(1) bond length is 1.26 Å. The C(6)-O(4) bond length is 1.24 Å. In the fifth C site, C(7) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. The C(7)-O(2) bond length is 1.26 Å. The C(7)-O(3) bond length is 1.24 Å. N(1) is bonded in a trigonal planar geometry to one Pr(1), one C(1), and one C(5) atom. H(3) is bonded in a single-bond geometry to one C(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Pr(1) and one C(6) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Pr(1) and one C(7) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Pr(1) and one C(7) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Pr(1) and one C(6) atom. Linkers: 16 [O]C(=O)c1cccc(C([O])=O)n1. Metal clusters: 16 [Pr].
