The crystal structure described by Yb3PbH2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 4-coordinate geometry to two equivalent Pb(1) and four equivalent H(1) atoms. In the second Yb site, Yb(2) is bonded in a 2-coordinate geometry to four equivalent Pb(1) and two equivalent H(1) atoms. Pb(1) is bonded in a 10-coordinate geometry to two equivalent Yb(1) and eight equivalent Yb(2) atoms. H(1) is bonded to two equivalent Yb(1) and two equivalent Yb(2) atoms to form a mixture of corner and edge-sharing HYb4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
