BaCO3 is Calcite-like structured and crystallizes in the trigonal R32 space group. Ba(1) is bonded to six equivalent O(1) atoms to form distorted corner-sharing BaO6 pentagonal pyramids. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to two equivalent Ba(1) and one C(1) atom.
