EuC6NH2O4CH crystallizes in the cubic Ia-3 space group. The structure consists of twenty-four 02329_fluka molecules inside a EuC6NH2O4 framework. In the EuC6NH2O4 framework, Eu(1) is bonded in a 5-coordinate geometry to one N(1), two equivalent O(1), and two equivalent O(2) atoms. The Eu(1)-N(1) bond length is 2.52 Å. Both Eu(1)-O(1) bond lengths are 2.39 Å. Both Eu(1)-O(2) bond lengths are 2.48 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.50 Å. The C(1)-O(1) bond length is 1.27 Å. The C(1)-O(2) bond length is 1.25 Å. In the second C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-C(2) bond length is 1.39 Å. The C(3)-H(1) bond length is 0.93 Å. In the third C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(3), and one N(1) atom. The C(2)-N(1) bond length is 1.34 Å. N(1) is bonded in a trigonal planar geometry to one Eu(1) and two equivalent C(2) atoms. H(1) is bonded in a single-bond geometry to one C(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Eu(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Eu(1) and one C(1) atom. Linkers: 24 [O]C(=O)c1cccc(C([O])=O)n1. Metal clusters: 24 [Eu].
