The compound described by CuSr(HCOO)4 crystallizes in the monoclinic P2/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(2) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one H(2), one O(3), and one O(4) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(2) atom. In the second O site, O(1) is bonded in a 2-coordinate geometry to one Sr(1), one Cu(1), and one C(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one C(2) atom. is represented by the CIF file [CIF]
