چکیده
The mononuclear copper title complex {N,N,N',N'-tetra-kis-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine-κ6N}copper(II) bis-(tetra-fluorido-borate), [Cu(C30H36N6)](BF4)2, is conveniently prepared from the reaction of Cu(BF4)2·6H2O with N,N,N',N'-tetra-kis-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine (tmpen) in aceto-nitrile at room temperature in air. The complex shows a distorted octa-hedral 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.
