The material structure described by Sr(ZnN)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one N(2) and three equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing ZnN4 tetrahedra. In the second Zn site, Zn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing ZnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to one Sr(2), two equivalent Sr(1), one Zn(2), and three equivalent Zn(1) atoms. In the second N site, N(2) is bonded in a 7-coordinate geometry to one Sr(2), two equivalent Sr(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. is represented by the CIF card [CIF]
