Structures and magnetic properties of copper(II) complexes containing tetrakis(2-pyridyl)methane

We designed spiro-fused dinculear complexes using tetrakis(2-pyridyl)methane (py4C) for the development of ground high-spin molecules. We attempted to prepare a dinuclear copper(II) complex [{Cu(hfac)2}2(py4C)], where hfac stands for 1,1,1,5,5,5-hexafluoropentane-2,4-dionate, but we obtained [Cu(hfac)2(py4C)] and [Cu(hfac)(py4C) · Cu(hfac)3]. These molecular structures were determined by the X-ray crystal structure analysis.
