Materials Data on Si2P4Ir by Materials Project
IrSi2P4 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two IrSi2P4 ribbons oriented in the (1, 0, 0) direction. Ir4+ is bonded in a linear geometry to two equivalent Si4- atoms. Both Ir–Si bond lengths are 2.43 Å. Si4- is bonded to one Ir4+, one Si4-, and two equivalent P1+ atoms to form distorted corner-sharing SiSiP2Ir tetrahedra. The Si–Si bond length is 2.32 Å. Both Si–P bond lengths are 2.30 Å. P1+ is bonded in a single-bond geometry to one Si4- atom.
