资源简介：
SmCoAsO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one CoAs sheet oriented in the (0, 0, 1) direction and one SmO sheet oriented in the (0, 0, 1) direction. In the CoAs sheet, Co2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing CoAs4 tetrahedra. All Co–As bond lengths are 2.30 Å. As3- is bonded in a 4-coordinate geometry to four equivalent Co2+ atoms. In the SmO sheet, Sm3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Sm–O bond lengths are 2.31 Å. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra.
