Abstract

Abstract : 1-D coordination polymers of alternating metal–metal bonded trinuclear [Co3 (dpa)4 ] 2+ building blocks and [MF6 ] 2− (M = Re, Zr, Sn) linkers have been structurally and magnetically characterized. 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 {Co3 6+ } and S = 3/2 Re IV magnetic sites through a single, unsupported fluoride bridge in1 .
