Abstract

(CuCl)2C4NCl3 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four C4NCl3 clusters and two CuCl ribbons oriented in the (1, 0, 0) direction. In each C4NCl3 cluster, there are four inequivalent C+1.50+ sites. In the first C+1.50+ site, C+1.50+ is bonded in a distorted linear geometry to two C+1.50+ atoms. Both C–C bond lengths are 1.29 Å. In the second C+1.50+ site, C+1.50+ is bonded in a trigonal planar geometry to one N3- and two Cl1- atoms. The C–N bond length is 1.28 Å. There is one shorter (1.71 Å) and one longer (1.73 Å) C–Cl bond length. In the third C+1.50+ site, C+1.50+ is bonded in a distorted single-bond geometry to one C+1.50+ and one Cl1- atom. The C–Cl bond length is 1.68 Å. In the fourth C+1.50+ site, C+1.50+ is bonded in a single-bond geometry to one C+1.50+ and one N3- atom. The C–N bond length is 1.23 Å. N3- is bonded in a bent 150 degrees geometry to two C+1.50+ atoms. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one C+1.50+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one C+1.50+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one C+1.50+ atom. In each CuCl ribbon, there are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded in a distorted linear geometry to two Cl1- atoms. Both Cu–Cl bond lengths are 2.13 Å. In the second Cu1+ site, Cu1+ is bonded in a 3-coordinate geometry to three Cl1- atoms. There are a spread of Cu–Cl bond distances ranging from 2.15–2.88 Å. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Cu1+ atoms. In the second Cl1- site, Cl1- is bonded in an L-shaped geometry to two Cu1+ atoms.
