SrH4(C2O3)2 crystallizes in the orthorhombic C222_1 space group. Sr(1) is bonded to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms to form distorted edge-sharing SrO8 hexagonal bipyramids. Both Sr(1)-O(1) bond lengths are 2.57 Å. Both Sr(1)-O(3) bond lengths are 2.53 Å. There are two shorter (2.58 Å) and two longer (2.66 Å) Sr(1)-O(2) bond lengths. There are two 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(2) atom. The C(1)-O(1) bond length is 1.27 Å. The C(1)-O(2) bond length is 1.27 Å. In the second C site, C(2) is bonded in a distorted water-like geometry to one H(1) and one O(3) atom. The C(2)-H(1) bond length is 1.10 Å. The C(2)-O(3) bond length is 1.42 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(3) atom. The H(2)-O(3) bond length is 1.00 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Sr(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Sr(1), one C(2), and one H(2) atom. Linkers: 2 [O]C(=O)[C@H](O)[C@@H](O)C([O])=O. Metal clusters: 2 [Sr].
