The material described by YPb2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 10-coordinate geometry to four equivalent Pb(2) and six equivalent Pb(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 8-coordinate geometry to six equivalent Y(1) and two equivalent Pb(1) atoms. In the second Pb site, Pb(2) is bonded in a 8-coordinate geometry to four equivalent Y(1) and four equivalent Pb(2) atoms. is represented by the CIF card [CIF]
