The material structure described by Nd3Zn11 crystallizes in the orthorhombic Immm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 16-coordinate geometry to two equivalent Zn(2), two equivalent Zn(4), six equivalent Zn(1), and six equivalent Zn(3) atoms. In the second Nd site, Nd(2) is bonded in a 16-coordinate geometry to four equivalent Zn(2), four equivalent Zn(3), and eight equivalent Zn(1) atoms. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 10-coordinate geometry to two equivalent Nd(2), three equivalent Nd(1), one Zn(1), one Zn(2), and three equivalent Zn(3) atoms. In the second Zn site, Zn(2) is bonded to two equivalent Nd(1), two equivalent Nd(2), two equivalent Zn(1), two equivalent Zn(4), and four equivalent Zn(3) atoms to form a mixture of distorted corner, face, and edge-sharing ZnNd4Zn8 cuboctahedra. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to one Nd(2), three equivalent Nd(1), one Zn(4), two equivalent Zn(2), and three equivalent Zn(1) atoms. In the fourth Zn site, Zn(4) is bonded to four equivalent Nd(1), four equivalent Zn(2), and four equivalent Zn(3) atoms to form face-sharing ZnNd4Zn8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
