Zn3In crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 10-coordinate geometry to six equivalent Zn(2) and four equivalent In(1) atoms. In the second Zn site, Zn(2) is bonded in a 10-coordinate geometry to three equivalent Zn(1), three equivalent Zn(2), and four equivalent In(1) atoms. In(1) is bonded to four equivalent Zn(1) and eight equivalent Zn(2) atoms to form a mixture of corner and face-sharing InZn12 cuboctahedra.
Zn3In crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 10-coordinate geometry to six equivalent Zn(2) and four equivalent In(1) atoms. There are two shorter (2.82 Å) and four longer (2.83 Å) Zn(1)-Zn(2) bond lengths. There are two shorter (2.98 Å) and two longer (3.03 Å) Zn(1)-In(1) bond lengths. In the second Zn site, Zn(2) is bonded in a 10-coordinate geometry to three equivalent Zn(1), three equivalent Zn(2), and four equivalent In(1) atoms. There is one shorter (2.75 Å) and two longer (2.86 Å) Zn(2)-Zn(2) bond lengths. There are a spread of Zn(2)-In(1) bond distances ranging from 2.99-3.07 Å. In(1) is bonded to four equivalent Zn(1) and eight equivalent Zn(2) atoms to form a mixture of corner and face-sharing InZn12 cuboctahedra.
