CuC4NH7OCl is Indium structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one CuC4NH7OCl cluster. Cu(1) is bonded to one C(1), one N(1), and two equivalent Cl(1) atoms to form distorted CuCNCl2 tetrahedra that share  a cornercorner with one C(4)H3N tetrahedra and  an edgeedge with one Cu(1)CNCl2 tetrahedra. The Cu(1)-C(1) bond length is 1.79 Å. The Cu(1)-N(1) bond length is 2.10 Å. Both Cu(1)-Cl(1) bond lengths are 2.38 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Cu(1) and one O(1) atom. The C(1)-O(1) bond length is 1.16 Å. In the second C site, C(2,3) is bonded in a distorted trigonal non-coplanar geometry to one N(1); one H(1,2); and one H(3,4) atom. The C(2,3)-N(1) bond length is 1.48 Å. The C(2,3)-H(1,2) bond length is 1.11 Å. The C(2,3)-H(3,4) bond length is 1.10 Å. In the third C site, C(4) is bonded to one N(1); one H(7); and two equivalent H(5,6) atoms to form CH3N tetrahedra that share  a cornercorner with one Cu(1)CNCl2 tetrahedra. The C(4)-N(1) bond length is 1.48 Å. The C(4)-H(7) bond length is 1.10 Å. Both C(4)-H(5,6) bond lengths are 1.09 Å. N(1) is bonded in a tetrahedral geometry to one Cu(1); one C(4); and two equivalent C(2,3) atoms. There are four inequivalent H sites. In the first H site, H(1,2) is bonded in a single-bond geometry to one C(2,3) atom. In the second H site, H(3,4) is bonded in a single-bond geometry to one C(2,3) atom. In the third H site, H(5,6) is bonded in a single-bond geometry to one C(4) atom. In the fourth H site, H(7) is bonded in a single-bond geometry to one C(4) atom. O(1) is bonded in a single-bond geometry to one C(1) atom. Cl(1) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms. Linkers: 1 CN1CCN(C)CC1. Metal clusters: 2 [Cu].
