The crystal structure described by La2(Rh3B2)3 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a 6-coordinate geometry to six equivalent Rh(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent B(1), and two equivalent B(2) atoms. In the second Rh site, Rh(2) is bonded in a distorted square co-planar geometry to four equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded to six equivalent Rh(1) atoms to form distorted edge-sharing BRh6 pentagonal pyramids. In the second B site, B(2) is bonded in a 6-coordinate geometry to three equivalent Rh(1) and three equivalent Rh(2) atoms. is represented by the CIF card [CIF]
