CH3Cu2C2N4H2SCl crystallizes in the monoclinic C2/c space group. The structure consists of eight 02329_fluka molecules inside a Cu2C2N4H2SCl framework. In the Cu2C2N4H2SCl framework, there are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to one N(1), one N(2), one S(1), and one Cl(1) atom to form corner-sharing CuSN2Cl tetrahedra. The Cu(1)-N(1) bond length is 2.00 Å. The Cu(1)-N(2) bond length is 2.01 Å. The Cu(1)-S(1) bond length is 2.24 Å. The Cu(1)-Cl(1) bond length is 2.35 Å. In the second Cu site, Cu(2) is bonded to one N(3), one N(4), and two equivalent Cl(1) atoms to form distorted CuN2Cl2 tetrahedra that share corners with two equivalent Cu(1)SN2Cl tetrahedra and  an edgeedge with one Cu(2)N2Cl2 tetrahedra. The Cu(2)-N(3) bond length is 1.98 Å. The Cu(2)-N(4) bond length is 1.97 Å. There is one shorter (2.37 Å) and one longer (2.45 Å) Cu(2)-Cl(1) bond length. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one N(1), one N(4), and one S(1) atom. The C(1)-N(1) bond length is 1.35 Å. The C(1)-N(4) bond length is 1.35 Å. The C(1)-S(1) bond length is 1.74 Å. In the second C site, C(2) is bonded in a distorted water-like geometry to one H(1), one H(2), and one S(1) atom. The C(2)-H(1) bond length is 1.10 Å. The C(2)-H(2) bond length is 1.10 Å. The C(2)-S(1) bond length is 1.83 Å. There are four inequivalent N sites. In the first N site, N(3) is bonded in a distorted trigonal planar geometry to one Cu(2), one N(2), and one N(4) atom. The N(3)-N(2) bond length is 1.32 Å. The N(3)-N(4) bond length is 1.35 Å. In the second N site, N(4) is bonded in a distorted trigonal planar geometry to one Cu(2), one C(1), and one N(3) atom. In the third N site, N(2) is bonded in a trigonal planar geometry to one Cu(1), one N(1), and one N(3) atom. The N(2)-N(1) bond length is 1.35 Å. In the fourth N site, N(1) is bonded in a 3-coordinate geometry to one Cu(1), one C(1), and one N(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. S(1) is bonded in a trigonal non-coplanar geometry to one Cu(1), one C(1), and one C(2) atom. Cl(1) is bonded in a distorted T-shaped geometry to one Cu(1) and two equivalent Cu(2) atoms.
