Cu2C3N3H3I2 crystallizes in the orthorhombic Cmc2_1 space group. Cu(1) is bonded to one N(1) and three equivalent I(1) atoms to form corner-sharing CuI3N tetrahedra. The Cu(1)-N(1) bond length is 2.01 Å. There are a spread of Cu(1)-I(1) bond distances ranging from 2.58-2.62 Å. There are two inequivalent C sites. In the first C site, 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 1.35 Å. The C(1)-N(2) bond length is 1.33 Å. The C(1)-H(1) bond length is 1.09 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to two equivalent N(1) and one H(2) atom. Both C(2)-N(1) bond lengths are 1.34 Å. The C(2)-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 trigonal planar geometry to one Cu(1), one C(1), and one C(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent C(1) atoms. There are two 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. I(1) is bonded in a trigonal non-coplanar geometry to three equivalent Cu(1) atoms. Linkers: 2 C1=NC=[N]=C[N]1. Metal clusters: 4 [Cu]. The MOF has largest included sphere 1.97 A, density 3.84 g/cm3, surface area 1943.41 m2/g, accessible volume 0.05 cm3/g
