Structural studies of the copper(II) acetate complexes Cu(O2CCH3)(2)(pyridine)(3) and Cu-6(mu-O2CCH3)(4)(mu(4)-O2CCH3)(2)(mu-OCMe3)(6)

[Cu(O-2-CH3)(2)](2), 1, reacts with pyridine to form violet-blue Cu(O2CCH3) (2)(pyridine)(3), 2, in >90% yield. 2 crystallizes from pyridine with a dis torted square-pyramidal geometry around copper with the monodentate acetate ligands located diagonally in the basal positions. 1 reacts with Bi(OCMe3) (3) in THF to form blue Cu-6(mu(4)-O2CCH3)(4)(mu-O2CCH3)(2)(mu-OCMe3)(6), 3 3 crystallizes from THF/hexanes with a hexagon of copper atoms linked by s ix doubly-bridging tert-butoxide ligands, four doubly-bridging bidentate ac etates, and two quadruply-bridging bidentate acetate ligands.
