Materials Data on CaBi2(CO)2 by Materials Project

CaC2(BiO)2 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two BiO sheets oriented in the (0, 0, 1) direction and two CaC2 sheets oriented in the (0, 0, 1) direction. In each BiO sheet, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Bi–O bond lengths are 2.33 Å. O2- is bonded to four equivalent Bi3+ atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In each CaC2 sheet, Ca2+ is bonded to eight equivalent C2- atoms to form a mixture of edge and face-sharing CaC8 hexagonal bipyramids. All Ca–C bond lengths are 2.74 Å. C2- is bonded in a 5-coordinate geometry to four equivalent Ca2+ and one C2- atom. The C–C bond length is 1.29 Å.
