The crystal structure described by LaZn4 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 17-coordinate geometry to four equivalent Zn(2), five equivalent Zn(3), and eight equivalent Zn(1) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 11-coordinate geometry to four equivalent La(1), two equivalent Zn(2), two equivalent Zn(3), and three equivalent Zn(1) atoms. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to four equivalent La(1), one Zn(3), and four equivalent Zn(1) atoms. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to five equivalent La(1), one Zn(2), and four equivalent Zn(1) atoms. is represented by the CIF card [CIF]
