The crystal structure described by Cu2Zn2Cl7CN crystallizes in the monoclinic Pc space group. The structure consists of two hydrogen cyanide molecules inside a Cu2Zn2Cl7 framework. In the Cu2Zn2Cl7 framework, there are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to one Cl(1), one Cl(3), one Cl(6), and one Cl(7) atom to form CuCl4 tetrahedra that share corners with two equivalent Cu(2)Cl4 tetrahedra, corners with two equivalent Zn(1)Cl4 tetrahedra, and corners with two equivalent Zn(2)Cl4 tetrahedra. In the second Cu site, Cu(2) is bonded to one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom to form CuCl4 tetrahedra that share  a cornercorner with one Zn(2)Cl4 tetrahedra, corners with two equivalent Cu(1)Cl4 tetrahedra, and corners with two equivalent Zn(1)Cl4 tetrahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one Cl(2), one Cl(3), one Cl(5), and one Cl(6) atom to form ZnCl4 tetrahedra that share corners with two equivalent Cu(1)Cl4 tetrahedra, corners with two equivalent Cu(2)Cl4 tetrahedra, and corners with two equivalent Zn(2)Cl4 tetrahedra. In the second Zn site, Zn(2) is bonded to one Cl(4), one Cl(5), one Cl(6), and one Cl(7) atom to form ZnCl4 tetrahedra that share  a cornercorner with one Cu(2)Cl4 tetrahedra, corners with two equivalent Cu(1)Cl4 tetrahedra, and corners with two equivalent Zn(1)Cl4 tetrahedra. There are seven inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one Cu(2) atom. In the second Cl site, Cl(2) is bonded in a bent 120 degrees geometry to one Cu(2) and one Zn(1) atom. In the third Cl site, Cl(3) is bonded in a trigonal non-coplanar geometry to one Cu(1), one Cu(2), and one Zn(1) atom. In the fourth Cl site, Cl(4) is bonded in a bent 120 degrees geometry to one Cu(2) and one Zn(2) atom. In the fifth Cl site, Cl(5) is bonded in a bent 120 degrees geometry to one Zn(1) and one Zn(2) atom. In the sixth Cl site, Cl(6) is bonded in a trigonal non-coplanar geometry to one Cu(1), one Zn(1), and one Zn(2) atom.
