Bis(μ-2-{5-[(pyridin-4-ylmethyl)sulfanyl]-1,3,4-oxadiazol-2-yl}phenolato)bis[(acetylacetonato)copper(II)]: a novel binuclear metallocycle
摘要:
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(C14H10N3O2S)(2)(C5H7O2)(2)] or Cu-2 L (2)(acac)(2) (acac is acetylacetonate). Each CuII centre is five-coordinate and adopts a square-pyramidal geometry. Two ligands are connected by two CuII 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...pi and pi-pi interactions.
