The crystal structure described by La3Rh2 crystallizes in the trigonal R-3 space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in an octahedral geometry to six equivalent Rh(1) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Rh(1) atoms. In the third La site, La(3) is bonded in a 5-coordinate geometry to five equivalent Rh(1) atoms. Rh(1) is bonded in a 8-coordinate geometry to one La(1), two equivalent La(2), and five equivalent La(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
