Multiredox Active [3 x 3] Copper Grids

A nonanuclear copper grid complex, [Cu-9(II)(L)(6)](BF4)(6)I-PrOH center dot 5H(2)(1 center dot 1-PrOH center dot 5H(2)O; L = 2,6-bis[5-(2-pyridinyl)-1H-pyrazol-3-yl]pyridine), was syn. thesized With a [3 X 3] grid structure consisting of nine Cu-II ions and Six deprotonated.ligands and displayed four, Steii 'quasi-reversible redox behavior from [Cu-9(II)] to [(Cu4Cu5II)-Cu-I]. The corresponding, heterovalent complex [(Cu2Cu7II)-Cu-I(L)(6)](PF6)(4)center dot 3H(2)O (2 center dot 3H(2)O) was successfully isolated and, had a distorted core structure that radically changed the intramolecular magnetic coupling pathways.
