KRuB4 crystallizes in the trigonal R3m space group. K(1) is bonded in a single-bond geometry to three equivalent Ru(1), one B(2), and six equivalent B(1) atoms. All K(1)-Ru(1) bond lengths are 2.76 Å. The K(1)-B(2) bond length is 0.64 Å. All K(1)-B(1) bond lengths are 2.93 Å. Ru(1) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent B(1) atoms. All Ru(1)-B(1) bond lengths are 2.23 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to two equivalent K(1), one Ru(1), one B(2), and two equivalent B(1) atoms. The B(1)-B(2) bond length is 1.36 Å. Both B(1)-B(1) bond lengths are 0.78 Å. In the second B site, B(2) is bonded in a single-bond geometry to one K(1) and three equivalent B(1) atoms.
