The title compound, Cu(2)(C(9)H(12)N(4))(3)(2), contains two Cu(I) ions, three bis-(1-methyl-imidazol-2-yl)methane (Me(2)BIM) ligands, and two trifluoromethanesulfonate anions in the asymmetric unit. Each Cu(I) ion has a distorted trigonal-planar geometry and is coordinated by two N atoms from the Me(2)BIM ligand and another N atom from the Me(2)BIM that acts as a bridging ligand, another N atom of the bridging Me(2)BIM being linked to the second Cu(I) ion. The imidazole rings of Me(2)BIM form intra-molecular π-π stacking inter-actions [centroid-centroid distances = 3.445 (2) and 3.547 (2) Å].
标题化合物Cu₂(C₉H₁₂N₄)₃₂的不对称单元中包含两个Cu(I)离子、三个双(1-甲基咪唑-2-基)甲烷(Me₂BIM)配体和两个三氟甲磺酸根阴离子。每个Cu(I)离子具有扭曲的三角平面几何构型，由来自Me₂BIM配体的两个N原子和来自作为桥联配体的Me₂BIM的另一个N原子配位，桥联Me₂BIM的另一个N原子与第二个Cu(I)离子相连。Me₂BIM的咪唑环形成分子内π-π堆积相互作用[质心-质心距离 = 3.445 (2) 和3.547 (2) Å]。
