Materials Data on MgCd(CO3)2 by Materials Project
CdMg(CO3)2 is Calcite-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form MgO6 octahedra that share corners with six equivalent CdO6 octahedra. The corner-sharing octahedral tilt angles are 62°. All Mg–O bond lengths are 2.11 Å. Cd2+ is bonded to six equivalent O2- atoms to form CdO6 octahedra that share corners with six equivalent MgO6 octahedra. The corner-sharing octahedral tilt angles are 62°. All Cd–O bond lengths are 2.36 Å. C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.30 Å. O2- is bonded in a distorted trigonal planar geometry to one Mg2+, one Cd2+, and one C4+ atom.
