One-dimensional coordination polymers of [Co3(dpa)4]2+ and [MF6]2- (M = ReIV, ZrIV and SnIV)

Abstract : One-dimensional coordination polymers of alternating metal–metal bonded trinuclear [Co3(dpa)4]2+ (dpa = the anion of 2,20-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/kB = +9.9 K) between S = 1/2 {Co3 6+} and S = 3/2 ReIV magnetic sites through a single, unsupported fluoride bridge in 1.
