Cu2C2N3H2Cl2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent N(1) and four equivalent Cl(1) atoms to form distorted edge-sharing CuN2Cl4 octahedra. Both Cu(1)-N(1) bond lengths are 1.94 Å. There are two shorter (2.44 Å) and two longer (2.85 Å) Cu(1)-Cl(1) bond lengths. In the second Cu site, Cu(2) is bonded in a trigonal planar geometry to one N(2) and two equivalent Cl(1) atoms. The Cu(2)-N(2) bond length is 1.93 Å. Both Cu(2)-Cl(1) bond lengths are 2.22 Å. C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. The C(1)-N(1) bond length is 1.33 Å. The C(1)-N(2) bond length is 1.36 Å. The C(1)-H(1) bond length is 1.08 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to one Cu(2) and two equivalent C(1) atoms. In the second N site, N(1) is bonded in a distorted trigonal planar geometry to one Cu(1), one C(1), and one N(1) atom. The N(1)-N(1) bond length is 1.37 Å. H(1) is bonded in a single-bond geometry to one C(1) atom. Cl(1) is bonded in a 3-coordinate geometry to one Cu(2) and two equivalent Cu(1) atoms. Linkers: 3 C1=NN=C[N]1. Metal clusters: 8 [Cu]. The MOF has largest included sphere 1.41 A, density 3.05 g/cm3, surface area 2658.15 m2/g, accessible volume 0.05 cm3/g
