ScCrPb is alpha Pu-derived structured and crystallizes in the triclinic P1 space group. Sc(1) is bonded in a 4-coordinate geometry to two equivalent Cr(1) and two equivalent Pb(1) atoms. There is one shorter (1.89 Å) and one longer (2.17 Å) Sc(1)-Cr(1) bond length. There is one shorter (2.27 Å) and one longer (2.30 Å) Sc(1)-Pb(1) bond length. Cr(1) is bonded in a 4-coordinate geometry to two equivalent Sc(1) and two equivalent Pb(1) atoms. There is one shorter (2.64 Å) and one longer (2.93 Å) Cr(1)-Pb(1) bond length. Pb(1) is bonded in a 4-coordinate geometry to two equivalent Sc(1) and two equivalent Cr(1) atoms.
