NdScB2 crystallizes in the trigonal R3m space group. Nd(1) is bonded in a 7-coordinate geometry to four equivalent Sc(1), three equivalent B(1), and three equivalent B(2) atoms. There is one shorter (1.94 Å) and three longer (3.12 Å) Nd(1)-Sc(1) bond lengths. All Nd(1)-B(1) bond lengths are 2.73 Å. All Nd(1)-B(2) bond lengths are 2.73 Å. Sc(1) is bonded in a 11-coordinate geometry to four equivalent Nd(1), three equivalent B(2), and four equivalent B(1) atoms. All Sc(1)-B(2) bond lengths are 2.73 Å. There is one shorter (2.59 Å) and three longer (2.81 Å) Sc(1)-B(1) bond lengths. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 8-coordinate geometry to three equivalent Nd(1), four equivalent Sc(1), and one B(2) atom. The B(1)-B(2) bond length is 1.94 Å. In the second B site, B(2) is bonded in a 7-coordinate geometry to three equivalent Nd(1), three equivalent Sc(1), and one B(1) atom.
