Eu2H30(C9O4)3(CH)6(CH2)3 crystallizes in the hexagonal P6_3cm space group. The structure consists of twelve 02329_fluka molecules and six 02329_fluka molecules inside a Eu2H30(C9O4)3 framework. In the Eu2H30(C9O4)3 framework, Eu(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. All Eu(1)-O(2) bond lengths are 2.39 Å. There are three shorter (2.42 Å) and three longer (2.60 Å) Eu(1)-O(1) bond lengths. There are five inequivalent C sites. In the first C site, C(2) is bonded to one C(1), one C(4), one C(5), and one C(7) atom to form corner-sharing CC4 tetrahedra. The C(2)-C(1) bond length is 1.52 Å. The C(2)-C(4) bond length is 1.54 Å. The C(2)-C(5) bond length is 1.54 Å. The C(2)-C(7) bond length is 1.55 Å. In the second C site, C(7) is bonded in a distorted water-like geometry to one C(2), one H(7), and one H(8) atom. The C(7)-H(7) bond length is 1.10 Å. The C(7)-H(8) bond length is 1.10 Å. In the third C site, C(4) is bonded in a distorted water-like geometry to two equivalent C(2), one H(2), and one H(3) atom. The C(4)-H(2) bond length is 1.10 Å. The C(4)-H(3) bond length is 1.10 Å. In the fourth 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)-O(1) bond length is 1.29 Å. The C(1)-O(2) bond length is 1.27 Å. In the fifth C site, C(5) is bonded in a distorted water-like geometry to one C(2), one H(4), and one H(5) atom. The C(5)-H(4) bond length is 1.10 Å. The C(5)-H(5) bond length is 1.10 Å. There are six inequivalent H sites. In the first H site, H(8) is bonded in a single-bond geometry to one C(7) atom. In the second H site, H(5) is bonded in a single-bond geometry to one C(5) atom. In the third H site, H(2) is bonded in a single-bond geometry to one C(4) atom. In the fourth H site, H(3) is bonded in a single-bond geometry to one C(4) atom. In the fifth H site, H(7) is bonded in a single-bond geometry to one C(7) atom. In the sixth H site, H(4) is bonded in a single-bond geometry to one C(5) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Eu(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Eu(1) and one C(1) atom. Linkers: 6 [O]C(=O)[C@]12C[C@H]3C[C@H](C[C@](C([O])=O)(C3)C1)C2. Metal clusters: 4 [Eu].
