RuCoB is half-Heusler structured and crystallizes in the trigonal R3m space group. Ru(1) is bonded to four equivalent Co(1) and three equivalent B(1) atoms to form distorted RuCo4B3 hexagonal pyramids that share corners with six equivalent Co(1)B4Ru4 hexagonal bipyramids, corners with four equivalent B(1)Co4Ru3 hexagonal pyramids, corners with six equivalent Ru(1)Co4B3 hexagonal pyramids, edges with three equivalent Co(1)B4Ru4 hexagonal bipyramids, edges with six equivalent Ru(1)Co4B3 hexagonal pyramids, and edges with six equivalent B(1)Co4Ru3 hexagonal pyramids. There are three shorter (2.14 Å) and one longer (2.72 Å) Ru(1)-Co(1) bond length. All Ru(1)-B(1) bond lengths are 2.20 Å. Co(1) is bonded to four equivalent Ru(1) and four equivalent B(1) atoms to form distorted CoB4Ru4 hexagonal bipyramids that share corners with six equivalent Ru(1)Co4B3 hexagonal pyramids, corners with six equivalent B(1)Co4Ru3 hexagonal pyramids, edges with twelve equivalent Co(1)B4Ru4 hexagonal bipyramids, edges with three equivalent Ru(1)Co4B3 hexagonal pyramids, and edges with three equivalent B(1)Co4Ru3 hexagonal pyramids. There are three shorter (2.14 Å) and one longer (2.72 Å) Co(1)-B(1) bond length. B(1) is bonded to three equivalent Ru(1) and four equivalent Co(1) atoms to form distorted BCo4Ru3 hexagonal pyramids that share corners with six equivalent Co(1)B4Ru4 hexagonal bipyramids, corners with four equivalent Ru(1)Co4B3 hexagonal pyramids, corners with six equivalent B(1)Co4Ru3 hexagonal pyramids, edges with three equivalent Co(1)B4Ru4 hexagonal bipyramids, edges with six equivalent Ru(1)Co4B3 hexagonal pyramids, and edges with six equivalent B(1)Co4Ru3 hexagonal pyramids.
