The reaction of CuX2 (X- not equal F-) salts with 1 equiv of 3-pyridyl-5-tert-butylpyrazole (HL) in basic methanol yields blue solids, from which disk complexes of the type [Cu-7(mu(3)-OH)(4)(mu-OR)(2)(mu-L)(6)](2+) and/or the cubane [Cu-4(mu(3)-OH)(4)(HL)(4)](4+) can be isolated by recrystallization under the appropriate conditions. Two of the disk complexes have been prepared in crystalline form: [Cu-7(mu(3)-OH)(4)(mu-OCH2CF3)(2)(mu-L)(6)][BF4](2) (2) and [Cu-7(mu(3)-OH)(4)(mu-OCH3)(2)-(mu-L)(6)]Cl-2 center dot xCH(2)Cl(2) (3 center dot xCH(2)Cl(2)). The molecular structures of both compounds as solvated crystals can be described as [Cu subset of Cu-6(mu-OH)(4)(mu-OR)(2)(mu-L)(6)](2+) (R = CH2CF3 or CH3) adducts. The [Cu-6(mu-OH)(4)(mu-OR)(2)(mu-L)(6)] ring is constructed of six square-pyramidal Cu ions, linked by 1,2-pyrazolido bridges from the L-ligands and by basal, apical-bridging hydroxy or alkoxy groups, while the central Cu ion is bound to the four metallamacrocyclic hydroxy donors in a near-regular square-planar geometry. The L- ligands project above and below the metal ion core, forming two bowl-shaped cavities that are fully (R = CH2CF3) or partially (R = CH3) occupied by the alkoxy R substituents. Variable-temperature magnetic susceptibility measurements on 2 demonstrated antiferromagnetic interactions between the Cu ions, yielding a spin-frustrated S=1/2 magnetic ground state that is fully populated below around 15 K. Electrospray ionization mass spectrometry, UV/vis/near-IR, and electron paramagnetic resonance measurements imply that the heptacopper(II) disk motif is robust in organic solvents.
