The material structure described by Pb3As crystallizes in the hexagonal P6_3/mmc space group. Pb(1) is bonded in a 8-coordinate geometry to six equivalent Pb(1) and two equivalent As(1) atoms. As(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. is represented by the CIF card [CIF]
