There are two inequivalent H sites. In the first H site, H(15,16) is bonded in a single-bond geometry to one C(11) atom. In the second H site, H(17,18) is bonded in a single-bond geometry to one C(15) atom. S(2) is bonded in a water-like geometry to one C(11) and one C(13) atom. In the Eu(CO2)3 cluster, Eu(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), one O(5), one O(6), and two equivalent O(2) atoms. The Eu(1)-O(1) bond length is 2.41 Å. The Eu(1)-O(3) bond length is 2.46 Å. The Eu(1)-O(4) bond length is 2.37 Å. The Eu(1)-O(5) bond length is 2.56 Å. The Eu(1)-O(6) bond length is 2.53 Å. There is one shorter (2.36 Å) and one longer (2.64 Å) Eu(1)-O(2) bond length. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(4) atom. The C(1)-O(1) bond length is 1.25 Å. The C(1)-O(4) bond length is 1.26 Å. In the second C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. The C(3)-O(2) bond length is 1.25 Å. The C(3)-O(3) bond length is 1.25 Å. In the third C site, C(12) is bonded in a distorted bent 120 degrees geometry to one O(5) and one O(6) atom. The C(12)-O(5) bond length is 1.24 Å. The C(12)-O(6) bond length is 1.27 Å. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Eu(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Eu(1) and one C(3) atom.
