Materials Data on CaMg(SiO)2 by Materials Project
CaMg(SiO)2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of two CaMg(SiO)2 ribbons oriented in the (0, 0, 1) direction. Ca2+ is bonded in a 2-coordinate geometry to two equivalent O2- atoms. Both Ca–O bond lengths are 2.36 Å. Mg2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (1.99 Å) and two longer (2.04 Å) Mg–O bond lengths. Si is bonded in a single-bond geometry to one O2- atom. The Si–O bond length is 1.70 Å. O2- is bonded to one Ca2+, two equivalent Mg2+, and one Si atom to form a mixture of distorted edge and corner-sharing OCaMg2Si trigonal pyramids.
