The crystal structure described by Zn2NCl crystallizes in the orthorhombic Pna2_1 space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent Cl(1) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent Cl(1) atoms. N(1) is bonded to two equivalent Zn(1) and two equivalent Zn(2) atoms to form NZn4 tetrahedra that share corners with four equivalent N(1)Zn4 tetrahedra and corners with eight equivalent Cl(1)Zn4 tetrahedra. Cl(1) is bonded to two equivalent Zn(1) and two equivalent Zn(2) atoms to form ClZn4 tetrahedra that share corners with four equivalent Cl(1)Zn4 tetrahedra and corners with eight equivalent N(1)Zn4 tetrahedra. is represented by the CIF file [CIF]
