Abstract

I was prepd. and reacted with CuX2 (X = ClO4, BF4, triflate) to give [Cu8L4(H2O)8]X16 (II). The bowed arrangement of bridging bidentate binding sites on I precludes a linear arrangement of metal ions. This conformation allows a spin-coupled octanuclear Cu(II) circular array of II to be formed from a single-stranded ligand. This circular array displays weak ferromagnetic exchange between metal centers and is a rare example of such an array contg. more than six centers. [on SciFinder (R)]
