Zn3(CrN2)2 crystallizes in the monoclinic C2/c space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of edge and corner-sharing CrN4 tetrahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one N(1) and two equivalent N(2) atoms. In the second Zn site, Zn(2) is bonded in a 6-coordinate geometry to two equivalent N(1) and four equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to two equivalent Cr(1), one Zn(1), and one Zn(2) atom. In the second N site, N(2) is bonded in a 6-coordinate geometry to two equivalent Cr(1), two equivalent Zn(1), and two equivalent Zn(2) atoms.
Zn3(CrN2)2 crystallizes in the monoclinic C2/c space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of edge and corner-sharing CrN4 tetrahedra. There is one shorter (1.88 Å) and one longer (1.92 Å) Cr(1)-N(1) bond length. There is one shorter (1.74 Å) and one longer (1.92 Å) Cr(1)-N(2) bond length. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one N(1) and two equivalent N(2) atoms. The Zn(1)-N(1) bond length is 2.00 Å. There is one shorter (2.32 Å) and one longer (2.60 Å) Zn(1)-N(2) bond length. In the second Zn site, Zn(2) is bonded in a 6-coordinate geometry to two equivalent N(1) and four equivalent N(2) atoms.
