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.

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. Both Yb(1)-Pb(1) bond lengths are 3.42 Å. All Yb(1)-H(1) bond lengths are 2.21 Å. 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. There are a spread of Yb(2)-Pb(1) bond distances ranging from 3.27-3.81 Å. Both Yb(2)-H(1) bond lengths are 2.20 Å. 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.
