CuC4NH4ClCH is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four 02329_fluka molecules and two CuC4NH4Cl clusters. In each CuC4NH4Cl cluster, Cu(1) is bonded in a 5-coordinate geometry to one C(4), one C(5), one N(1), and two equivalent Cl(1) atoms. The Cu(1)-C(4) bond length is 2.12 Å. The Cu(1)-C(5) bond length is 2.06 Å. The Cu(1)-N(1) bond length is 1.93 Å. There is one shorter (2.29 Å) and one longer (2.49 Å) Cu(1)-Cl(1) bond length. There are four inequivalent C sites. In the first C site, C(4) is bonded in a distorted single-bond geometry to one Cu(1) and one H(3) atom. The C(4)-H(3) bond length is 1.09 Å. In the second C site, C(5) is bonded in a distorted bent 120 degrees geometry to one Cu(1), one H(4), and one H(5) atom. The C(5)-H(4) bond length is 1.09 Å. The C(5)-H(5) bond length is 1.09 Å. In the third C site, C(1) is bonded in a distorted linear geometry to one C(2) and one N(1) atom. The C(1)-C(2) bond length is 1.40 Å. The C(1)-N(1) bond length is 1.17 Å. In the fourth C site, C(2) is bonded in a distorted single-bond geometry to one C(1) and one H(1) atom. The C(2)-H(1) bond length is 1.09 Å. N(1) is bonded in a linear geometry to one Cu(1) and one C(1) atom. There are four 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(3) is bonded in a single-bond geometry to one C(4) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(5) atom. In the fourth H site, H(5) is bonded in a single-bond geometry to one C(5) atom. Cl(1) is bonded in an L-shaped geometry to two equivalent Cu(1) atoms. Linkers: 4 C=C/C=C/C#N. Metal clusters: 4 [Cu]. The MOF has largest included sphere 1.91 A, density 1.92 g/cm3, surface area 4101.75 m2/g, accessible volume 0.11 cm3/g
