Abstract

One-dimensional coordination polymers of alternating metal–metal bonded trinuclear [Co₃(dpa)₄]²⁺ (dpa = the anion of 2,2′-dipyridylamine) building blocks and [ReF₆]²⁻ (1), [ZrF₆]²⁻ (2) or [SnF₆]²⁻ (3) linkers have been self-assembled and crystallographically characterized. Magnetic measurements reveal a significant ferromagnetic coupling (J/k_B = +9.9 K) between S = 1/2 {Co₃⁶⁺} and S = 3/2 Re^IV magnetic sites through a single, unsupported fluoride bridge in 1.
