Cu2C3N2H6Cl3 crystallizes in the hexagonal P6_3mc space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to one N(1), one Cl(1), and two equivalent Cl(2) atoms to form distorted CuNCl3 trigonal pyramids that share  a cornercorner with one Cu(2)NCl3 tetrahedra,  a cornercorner with one C(1)H2N2 tetrahedra, corners with two equivalent C(2)H2N2 tetrahedra, and corners with two equivalent Cu(1)NCl3 trigonal pyramids. The Cu(1)-N(1) bond length is 2.19 Å. The Cu(1)-Cl(1) bond length is 2.37 Å. Both Cu(1)-Cl(2) bond lengths are 2.33 Å. In the second Cu site, Cu(2) is bonded to one N(2) and three equivalent Cl(1) atoms to form CuNCl3 tetrahedra that share corners with three equivalent C(1)H2N2 tetrahedra and corners with three equivalent Cu(1)NCl3 trigonal pyramids. The Cu(2)-N(2) bond length is 2.16 Å. All Cu(2)-Cl(1) bond lengths are 2.39 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded to one N(1), one N(2), and two equivalent H(1) atoms to form distorted CH2N2 tetrahedra that share  a cornercorner with one Cu(2)NCl3 tetrahedra, corners with two equivalent C(1)H2N2 tetrahedra, corners with two equivalent C(2)H2N2 tetrahedra, and  a cornercorner with one Cu(1)NCl3 trigonal pyramid. The C(1)-N(1) bond length is 1.51 Å. The C(1)-N(2) bond length is 1.46 Å. Both C(1)-H(1) bond lengths are 0.98 Å. In the second C site, C(2) is bonded to two equivalent N(1), one H(2), and one H(3) atom to form CH2N2 tetrahedra that share corners with two equivalent C(1)H2N2 tetrahedra, corners with two equivalent C(2)H2N2 tetrahedra, and corners with two equivalent Cu(1)NCl3 trigonal pyramids. Both C(2)-N(1) bond lengths are 1.47 Å. The C(2)-H(2) bond length is 0.97 Å. The C(2)-H(3) bond length is 0.96 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cu(1), one C(1), and two equivalent C(2) atoms to form distorted corner-sharing NCuC3 tetrahedra. In the second N site, N(2) is bonded to one Cu(2) and three equivalent C(1) atoms to form corner-sharing NCuC3 tetrahedra. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in an L-shaped geometry to one Cu(1) and one Cu(2) atom. In the second Cl site, Cl(2) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms.
