SrC8H6O7 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 9-coordinate geometry to one O(4), two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. The Sr(1)-O(4) bond length is 2.59 Å. Both Sr(1)-O(1) bond lengths are 2.67 Å. Both Sr(1)-O(3) bond lengths are 2.74 Å. There are two shorter (2.55 Å) and two longer (2.77 Å) Sr(1)-O(2) bond lengths. There are four inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(4) atom. The C(2)-C(1) bond length is 1.49 Å. The C(2)-C(3) bond length is 1.42 Å. The C(2)-C(4) bond length is 1.40 Å. In the second C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one O(3) atom. The C(3)-O(3) bond length is 1.37 Å. In the third C site, C(4) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(4)-H(1) bond length is 1.09 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. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(4) atom. In the second H site, H(2) is bonded in a bent 150 degrees geometry to one O(1) and one O(3) atom. The H(2)-O(1) bond length is 1.49 Å. The H(2)-O(3) bond length is 1.04 Å. In the third H site, H(3) is bonded in a single-bond geometry to one O(4) atom. The H(3)-O(4) bond length is 0.98 Å. There are four inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom. In the second O site, O(3) is bonded in a distorted water-like geometry to one Sr(1), one C(3), and one H(2) atom. In the third O site, O(4) is bonded in a water-like geometry to one Sr(1) and two equivalent H(3) atoms. In the fourth O site, O(1) is bonded in a distorted water-like geometry to one Sr(1), one C(1), and one H(2) atom. Linkers: 2 [O]C(=O)c1cc(O)c(C([O])=O)cc1O. Metal clusters: 2 [Sr]. RCSR code: htp.
