【 摘 要 】

The mononuclear copper title complex {N,N,N′,N′-tetra­kis­[(6-methyl­pyridin-2-yl)meth­yl]ethane-1,2-di­amine-κ6N}copper(II) bis­(tetra­fluorido­borate), [Cu(C30H36N6)](BF4)2, is conveniently prepared from the reaction of Cu(BF4)2·6H2O with N,N,N′,N′-tetra­kis­[(6-methyl­pyridin-2-yl)meth­yl]ethane-1,2-di­amine (tmpen) in aceto­nitrile at room temperature in air. The complex shows a distorted octa­hedral environment around the CuII cation (site symmetry 2) and adopts the centrosymmetric space group C2/c. The presence of the 6-methyl substituent hinders the approach of the pyridine group to the CuII core. The bond lengths about the CuII atom are significantly longer than those of analogues without the 6-methyl substituents.
