Abstract top

The title compound, [Cu2(C9H12N4)3](CF3SO3)2, contains two CuI ions, three bis(1-methylimidazol-2-yl)methane (Me2BIM) ligands, and two trifluoromethanesulfonate anions in the asymmetric unit. Each CuI ion has a distorted trigonal-planar geometry and is coordinated by two N atoms from the Me2BIM ligand and another N atom from the Me2BIM that acts as a bridging ligand, another N atom of the bridging Me2BIM being linked to the second CuI ion. The imidazole rings of Me2BIM form intramolecular [pi]-[pi] stacking interactions [centroid-centroid distances = 3.445 (2) and 3.547 (2) Å].

Comment top

Ligand bis(imidazol-2-yl)methane derivative is a bidentate ligand, either chelating one metal center or bridging two metals. The crystal structures of CuII complexes with bis(imidazol-2-yl)methane (BIM) and bis(1-methylimidazol-2-yl)methane (Me2BIM) have been reported by Place et al. (1998), Abuskhuna et al. (2004a), respectively. In addition, that of AgI complex with BIM has been reported by Abuskhuna et al. (2004b). The CuII complexes have four- or six-coordinate structure that is coordinated with two Me2BIM ligands, and the AgI complex forms a two-coordinate structure bridged by BIM. The title compound, [(µ-Me2BIM){Cu(Me2BIM)}2](OTf)2, contains two CuI ions, three bis(1-methylimidazol-2-yl)methane (Me2BIM) ligands, and two trifluoromethanesulfonate anions as an independent unit in the unit cell. Each CuI ion has a distorted trigonal planar geometry coordinated with two N atoms from Me2BIM and one N atom from a bridging Me2BIM ligand, and an N atom from an additional bridging Me2BIM which is linked to another CuI ion. This is a novel dinuclear CuI complex with Me2BIM. An intramolecular π—π stackings are formed between the imidazol rings; angles between the imidazole ring 1 containing N(1) and the ring 2 containing N(7) and between the ring 3 containing N(5) and the ring 4 containing N(9) are 4.4 (1) and 2.2 (2)°, respectively, and distances of the centroid of plane 1 to plane 2 and that of plane 3 to plane 4 are 3.445 (2) and 3.547 (2) Å, respectively.

For the protonated ligand Me2BIM, see: Messerle et al. (2003). For coordination complexes with one or two Me2BIM ligands chelating one metal center, see: Elgafi et al. (1999); Abuskhuna et al. (2004a); Burling et al. (2004); Kennedy et al. (2007); Dabb et al. (2009). For CuII complexes with two BIM ligands chelating one metal center, see: Place et al. (1998). For AgI complexes with two BIM ligands bridging two metals, see: Abuskhuna et al. (2004b). The Me2BIM ligand was synthesized by modified literature methods (Byers & Canty, 1990; Elgafi et al., 1997).

Experimental top

Ligand Me2BIM was synthesized by modifying the literature methods of Byers et al. (1990) and Elgafi et al. (1997). Ligand Me2BIM (1.13 mmol, 200 mg) in CH2Cl2 (4 ml) was added into a MeCN solution (3 ml) of [Cu(MeCN)4](OTf) (1.15 mmol, 433 mg). The mixture was stirred for 1 h at room temperature in a glovebox ([O2] < 1 p.p.m. and [H2O] < 1 p.p.m.). After addition of Et2O (7 ml), the resulting precipitates were collected by filtration and dried to give an yellow powder in a 65% yield. Single crystals suitable for X-ray crystallographic analysis were obtained by recrystallization from CH2Cl2/MeCN/Et2O.

Refinement top

Hydrogen atoms attached to carbon atoms were positioned geometrically and treated as riding with aromatic C—H = 0.95 Å, methyl C—H = 0.98 Å, and methylenic C—H = 0.99 Å and with Uiso(H) = 1.2Ueq(C).

Special details top

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt).
