The crystal structure described by LaNi3B crystallizes in the orthorhombic Cmcm space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), four equivalent Ni(2), four equivalent Ni(3), one B(2), and one B(3) atom. In the second La site, La(2) is bonded in a 14-coordinate geometry to four equivalent Ni(4), eight equivalent Ni(2), and two equivalent B(1) atoms. In the third La site, La(3) is bonded in a 14-coordinate geometry to four equivalent Ni(4), eight equivalent Ni(1), and two equivalent B(1) atoms. There are four inequivalent Ni sites. In the first Ni site, Ni(3) is bonded in a distorted linear geometry to four equivalent La(1), one B(2), and one B(3) atom. In the second Ni site, Ni(4) is bonded in a distorted linear geometry to two equivalent La(2), two equivalent La(3), and two equivalent B(1) atoms. In the third Ni site, Ni(1) is bonded in a 2-coordinate geometry to two equivalent La(1), two equivalent La(3), one B(1), and one B(2) atom. In the fourth Ni site, Ni(2) is bonded in a 2-coordinate geometry to two equivalent La(1), two equivalent La(2), one B(1), and one B(3) atom. There are three inequivalent B sites. In the first B site, B(1) is bonded in a 8-coordinate geometry to one La(2), one La(3), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Ni(4) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent Ni(3), and four equivalent Ni(1) atoms. In the third B site, B(3) is bonded in a 8-coordinate geometry to two equivalent La(1), two equivalent Ni(3), and four equivalent Ni(2) atoms. is represented by the CIF card [CIF]
