The title compound, (C₁₀H₂₁N₃)[CuCl₄], is composed of one 1-[2-(diethylazaniumyl)ethyl]-3-methylimidazolium dication and a tetrachloridocuprate(II) dianion. The anion adopts a distorted tetrahedral geometry. Bifurcated interionic N—H⋯Cl hydrogen bonds and several C—H⋯Cl contacts are observed, leading to a layer-like arrangement of the components parallel to (100).

Keywords: crystal structure; copper(II) complex; tetrachloridocuprate; 1-[2-(diethylazaniumyl)ethyl]-3-methylimidazolium dication; hydrogen bonding.

Comment top

1-[2-(Diethylazaniumyl)ethyl]-3-methylimidazolium ions in deprotonated form can act as bidentate ligands (Laus et al., 2012). In this work, it is shown that they are also capable of coordinating in protonated form. The structure of the ion pair of 3-(2-(diethylammonio)ethyl-1- methylimidazolium tetrachlorocuprate (II) is shown in Figure 1. The anion adopts a distorted tetrahedral geometry. The Cl—Cu—Cl angles range from 97° to 134°. The heterocyclic rings of the cation are oriented parallel to the (3 7 2) and (3 7 2) planes with an interplanar angle of 32.5°. The side chain is twisted out of the heterocyclic ring plane. In the crystal structure, the cations and anions are linked by N—H···Cl and C—H···Cl hydrogen bonds (Figure 2).

Experimental top

The title compound, (C₁₀H₂₁N₃)CuCl₄, was obtained from the reaction of bis-(1-(2-(diethylamino)ethyl)-3-methylimidazolin-2-ylidene) di-silver(I) bis(bis(triflimide)) (Laus et al., 2012) and carbonyl chlorocopper(I) (Håkansson & Jagner, 1990) in methanol under ambient conditions. This unconventional synthesis involves redox, protonation and complexation steps. Yellow-green single crystals were obtained from MeOH in modest yield. Melting point 118–120 °C.

Special details top

Experimental. Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
