Sr2CuCO5 crystallizes in the orthorhombic Pmm2 space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Cu(1) is bonded in a distorted square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Cu(1) atoms. In the second O site, O(2) is bonded to four equivalent Sr(1) and two equivalent Cu(1) atoms to form a mixture of edge and corner-sharing OSr4Cu2 octahedra. The corner-sharing octahedra are not tilted. In the third O site, O(3) is bonded in a single-bond geometry to four equivalent Sr(1) and one C(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom.
