Materials Data on SiPd2 by Materials Project

Pd2Si crystallizes in the hexagonal P-62m space group. The structure is two-dimensional and consists of one Pd3Si ribbon oriented in the (0, 0, 1) direction and one Pd3Si2 sheet oriented in the (0, 0, 1) direction. In the Pd3Si ribbon, Pd2+ is bonded in a 2-coordinate geometry to two equivalent Si4- atoms. Both Pd–Si bond lengths are 2.39 Å. Si4- is bonded in a 6-coordinate geometry to six equivalent Pd2+ atoms. In the Pd3Si2 sheet, Pd2+ is bonded in a bent 150 degrees geometry to two equivalent Si4- atoms. Both Pd–Si bond lengths are 2.37 Å. Si4- is bonded in a distorted trigonal planar geometry to three equivalent Pd2+ atoms.
