Ru2B3 is alpha boron-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ru(1) is bonded in a 7-coordinate geometry to three equivalent B(1) and four equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded to six equivalent Ru(1) atoms to form distorted edge-sharing BRu6 pentagonal pyramids. In the second B site, B(2) is bonded in a 7-coordinate geometry to four equivalent Ru(1) and three equivalent B(2) atoms.
Ru2B3 is alpha boron-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ru(1) is bonded in a 7-coordinate geometry to three equivalent B(1) and four equivalent B(2) atoms. All Ru(1)-B(1) bond lengths are 2.19 Å. There is one shorter (2.18 Å) and three longer (2.19 Å) Ru(1)-B(2) bond lengths. There are two inequivalent B sites. In the first B site, B(1) is bonded to six equivalent Ru(1) atoms to form distorted edge-sharing BRu6 pentagonal pyramids. In the second B site, B(2) is bonded in a 7-coordinate geometry to four equivalent Ru(1) and three equivalent B(2) atoms. All B(2)-B(2) bond lengths are 1.85 Å.
