CuC5N2H7Cl is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one CuC5N2H7Cl cluster. Cu(1) is bonded to one N(1), one N(2), and two equivalent Cl(1) atoms to form distorted edge-sharing CuN2Cl2 tetrahedra. The Cu(1)-N(1) bond length is 2.11 Å. The Cu(1)-N(2) bond length is 1.89 Å. There is one shorter (2.37 Å) and one longer (2.40 Å) Cu(1)-Cl(1) bond length. There are five inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one C(2) and one N(2) atom. The C(1)-C(2) bond length is 1.44 Å. The C(1)-N(2) bond length is 1.17 Å. In the second C site, C(2) is bonded in a distorted trigonal non-coplanar geometry to one C(1), one H(3), one H(4), and one H(5) atom. The C(2)-H(3) bond length is 1.10 Å. The C(2)-H(4) bond length is 1.10 Å. The C(2)-H(5) bond length is 1.10 Å. In the third C site, C(3) is bonded in a distorted trigonal planar geometry to one C(4), one C(5), and one N(1) atom. The C(3)-C(4) bond length is 1.40 Å. The C(3)-C(5) bond length is 1.40 Å. The C(3)-N(1) bond length is 1.43 Å. In the fourth C site, C(4) is bonded in a distorted single-bond geometry to one C(3) and one H(1) atom. The C(4)-H(1) bond length is 1.09 Å. In the fifth C site, C(5) is bonded in a distorted single-bond geometry to one C(3) and one H(2) atom. The C(5)-H(2) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted tetrahedral geometry to one Cu(1), one C(3), one H(6), and one H(7) atom. The N(1)-H(6) bond length is 1.03 Å. The N(1)-H(7) bond length is 1.03 Å. In the second N site, N(2) is bonded in a bent 150 degrees geometry to one Cu(1) and one C(1) atom. There are seven inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(5) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(2) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one N(1) atom. In the seventh H site, H(7) is bonded in a single-bond geometry to one N(1) atom. Cl(1) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms. Linkers: 1 Nc1ccc(N)cc1.
