MgCO3 is Calcite structured and crystallizes in the trigonal R-3c space group. Mg(1) is bonded to six equivalent O(1) atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 59°. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent Mg(1) and one C(1) atom.
