Nd(RuB)2 crystallizes in the triclinic P1 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 2-coordinate geometry to one Ru(3), one Ru(4), and one B(1) atom. The Nd(1)-Ru(3) bond length is 1.21 Å. The Nd(1)-Ru(4) bond length is 1.80 Å. The Nd(1)-B(1) bond length is 1.54 Å. In the second Nd site, Nd(2) is bonded in a distorted bent 150 degrees geometry to one Ru(1), one Ru(2), one B(2), and one B(3) atom. The Nd(2)-Ru(1) bond length is 2.37 Å. The Nd(2)-Ru(2) bond length is 1.78 Å. The Nd(2)-B(2) bond length is 2.61 Å. The Nd(2)-B(3) bond length is 1.54 Å. There are four inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 4-coordinate geometry to one Nd(2), one Ru(2), one B(1), and one B(4) atom. The Ru(1)-Ru(2) bond length is 1.52 Å. The Ru(1)-B(1) bond length is 2.34 Å. The Ru(1)-B(4) bond length is 2.31 Å. In the second Ru site, Ru(2) is bonded in a distorted single-bond geometry to one Nd(2), one Ru(1), one Ru(4), and one B(2) atom. The Ru(2)-Ru(4) bond length is 1.84 Å. The Ru(2)-B(2) bond length is 2.34 Å. In the third Ru site, Ru(3) is bonded in a single-bond geometry to one Nd(1), one Ru(4), and one B(4) atom. The Ru(3)-Ru(4) bond length is 1.52 Å. The Ru(3)-B(4) bond length is 2.34 Å. In the fourth Ru site, Ru(4) is bonded in a distorted rectangular see-saw-like geometry to one Nd(1), one Ru(2), one Ru(3), and one B(3) atom. The Ru(4)-B(3) bond length is 2.34 Å. There are four inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one Nd(1), one Ru(1), and one B(2) atom. The B(1)-B(2) bond length is 2.07 Å. In the second B site, B(2) is bonded in a 3-coordinate geometry to one Nd(2), one Ru(2), and one B(1) atom. In the third B site, B(3) is bonded in a single-bond geometry to one Nd(2), one Ru(4), and one B(4) atom. The B(3)-B(4) bond length is 2.07 Å. In the fourth B site, B(4) is bonded in a 3-coordinate geometry to one Ru(1), one Ru(3), and one B(3) atom.
