Bis(μ-2-{5-[(pyridin-4-ylmethyl)sulfanyl]-1,3,4-oxadiazol-2-yl}phenolato)bis[(acetylacetonato)copper(II)]: a novel binuclear metallocycle.

The new asymmetric ligand 2-{5-[(pyridin-4-ylmethyl)sulfanyl]-1,3,4-oxadiazol-3-yl}phenol (HL) has been used to synthesize the novel discrete title binuclear metallocycle, [Cu(2)(C(14)H(10)N(3)O(2)S)(2)(C(5)H(7)O(2))(2)] or Cu(2)L(2)(acac)(2) (acac is acetylacetonate). Each Cu(II) centre is five-coordinate and adopts a square-pyramidal geometry. Two ligands are connected by two Cu(II) cations to form the dinuclear metallocycle, which lies across a crystallographic inversion centre. Discrete molecules are linked into a two-dimensional structure through weak Cu···S, C-H···π and π-π interactions.
