B6Cr2Nd crystallizes in the orthorhombic Immm space group. Nd(1) is bonded in a 16-coordinate geometry to four equivalent B(1) and twelve equivalent B(2) atoms. Cr(1) is bonded in a 10-coordinate geometry to four equivalent B(1) and six equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1), three equivalent Cr(1), one B(1), and two equivalent B(2) atoms. In the second B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Cr(1), one B(1), and two equivalent B(2) atoms.
B6Cr2Nd crystallizes in the orthorhombic Immm space group. Nd(1) is bonded in a 16-coordinate geometry to four equivalent B(1) and twelve equivalent B(2) atoms. All Nd(1)-B(1) bond lengths are 2.83 Å. There are eight shorter (2.85 Å) and four longer (2.96 Å) Nd(1)-B(2) bond lengths. Cr(1) is bonded in a 10-coordinate geometry to four equivalent B(1) and six equivalent B(2) atoms. All Cr(1)-B(1) bond lengths are 2.21 Å. There are two shorter (2.13 Å) and four longer (2.22 Å) Cr(1)-B(2) bond lengths. There are two inequivalent B sites. In the first B site, B(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1), three equivalent Cr(1), one B(1), and two equivalent B(2) atoms. The B(2)-B(1) bond length is 1.77 Å. Both B(2)-B(2) bond lengths are 1.79 Å. In the second B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Cr(1), one B(1), and two equivalent B(2) atoms.
