The material structure described by SrCO3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded in a 10-coordinate geometry to four equivalent O(1) and six equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Sr(2), two equivalent Sr(1), and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Sr(2) and one C(1) atom. is represented by the CIF file [CIF]
