Abstract

TmC4N2Cl5(ClCCN)2 crystallizes in the orthorhombic P2_12_12 space group. The structure is one-dimensional and consists of four chloromethyl(methylidyne)azanium molecules and two TmC4N2Cl5 ribbons oriented in the (0, 1, 0) direction. In each TmC4N2Cl5 ribbon, Tm3+ is bonded in a distorted tetrahedral geometry to four Cl1- atoms. There are two shorter (2.43 Å) and two longer (2.56 Å) Tm–Cl bond lengths. There are two inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a water-like geometry to one N3- and one Cl1- atom. The C–N bond length is 1.25 Å. The C–Cl bond length is 2.33 Å. In the second C2+ site, C2+ is bonded in a bent 120 degrees geometry to one N3- and one Cl1- atom. The C–N bond length is 1.27 Å. The C–Cl bond length is 1.96 Å. N3- is bonded in a linear geometry to two C2+ atoms. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Tm3+ atom. In the second Cl1- site, Cl1- is bonded in a bent 150 degrees geometry to two equivalent C2+ atoms. In the third Cl1- site, Cl1- is bonded in a water-like geometry to one Tm3+ and one C2+ atom.
