{μ-Bis(1-methylimidazol-2-yl)methane-κ2N3:N3′}bis{[(1-methylimidazol-2-yl)methane-κ2N3,N3′]copper(I)} bis(trifluoromethanesulfonate)

Abstract

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 π–π stacking interactions [centroid–centroid distances = 3.445 (2) and 3.547 (2) Å].
