Materials Data on K2SiP2 by Materials Project
K2SiP2 crystallizes in the orthorhombic Ibam space group. The structure is one-dimensional and consists of eight kalium molecules and two SiP2 ribbons oriented in the (1, 0, 0) direction. In each SiP2 ribbon, Si4- is bonded in a 4-coordinate geometry to four equivalent P1+ atoms. All Si–P bond lengths are 2.29 Å. P1+ is bonded in an L-shaped geometry to two equivalent Si4- atoms.
