Th3Ni4In13 crystallizes in the cubic Pm-3n space group. Th(1) is bonded in a 16-coordinate geometry to four equivalent Ni(1) and twelve equivalent In(2) atoms. Ni(1) is bonded in a 6-coordinate geometry to three equivalent Th(1) and six equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(2) is bonded in a 2-coordinate geometry to three equivalent Th(1), two equivalent Ni(1), and one In(1) atom. In the second In site, In(1) is bonded in a cuboctahedral geometry to twelve equivalent In(2) atoms.
