The compound described by 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. is represented by the CIF file [CIF]
