Materials Data on Mg(C2O3)2 by Materials Project
Mg(CO3)2(C)2 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of four ethyne molecules and two Mg(CO3)2 sheets oriented in the (1, 0, 0) direction. In each Mg(CO3)2 sheet, Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.04–2.16 Å. C+2.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one C+2.50+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Mg2+ and one C+2.50+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Mg2+ atom.
