Abstract

The reaction of $2,2^\prime$-bipyridine (bipy) with $[Cu_2(O_2CMe)_4(H_2O)_2]$ in ethanol follwed by $NH_4PF_6$ yields an unique trinuclear copper(II) species, $[Cu_3(O_2CMe)_4(H_2O)(bipy)_3][PF_6]_2$, the crystal structure of which shows the smallest monoatomic acetate bridge Cu-O-Cu angle of $92.9(1)^0$ and four different acetate co-ordination modes; in methanol glass at 77 K it exhibits an X-band ESR spectrum characteristic of a strongly coupled dicopper(II) unit and a normal copper(II) centre.
