Abstract

A cyanide-bridged molecular square, [Co₂Fe₂(CN) ₆(tp*)_2- (dtbbpy)₄](PF₆) ₂·2MeOH (1) (tp* = hydrotris(3,5-dimethylpyrazol-1-yl) borate and dtbbpy = 4,4′-di-tert-butyl-2,2′-bipyridine) was prepared by the reaction of (Bu₄N)[Fe(CN)₃(tp*)] with Co(CF₃SO₃)₂·6H₂O and dtbbpy in methanol. Variable temperature X-ray structural analyses, magnetic and spectroscopic data revealed that 1 exhibited novel thermal two-stepped spin transitions induced by intramolecular electron transfers.
