YScNbPb crystallizes in the trigonal R3m space group. Y(1) is bonded in a 10-coordinate geometry to three equivalent Sc(1), four equivalent Nb(1), and three equivalent Pb(1) atoms. All Y(1)-Sc(1) bond lengths are 2.99 Å. There is one shorter (2.57 Å) and three longer (3.33 Å) Y(1)-Nb(1) bond lengths. All Y(1)-Pb(1) bond lengths are 3.09 Å. Sc(1) is bonded in a distorted single-bond geometry to three equivalent Y(1) and four equivalent Pb(1) atoms. There is one shorter (2.57 Å) and three longer (3.33 Å) Sc(1)-Pb(1) bond lengths. Nb(1) is bonded in a distorted linear geometry to four equivalent Y(1) and four equivalent Pb(1) atoms. There is one shorter (2.57 Å) and three longer (3.33 Å) Nb(1)-Pb(1) bond lengths. Pb(1) is bonded in a 11-coordinate geometry to three equivalent Y(1), four equivalent Sc(1), and four equivalent Nb(1) atoms.
