Abstract

The self-assembly of CuX₂ (X⁻ = Cl⁻, Br⁻, NO₃⁻, ClO₄⁻, and BF₄⁻) with a new diallylbis(pyridin-3-yl)silane ligand (L) gives rise to the similar 2D coordination networks with composition of Cu(II) and L of 1: 2 irrespective of anions and solvents. The 2D networks of [CuCl₂L₂]·2H₂O, [CuBr₂L₂]·2H₂O, and [Cu(H₂O)₂L₂]·(NO₃)₂ are packed in a staggered mode while the similar networks of [Cu(BF₄)₂L₂] and [Cu(ClO₄)₂L₂] are arrayed in a eclipsed fashion. These crystals of all 2D networks have been employed as catalysts for 3,5-di-tert-butylcatechol (3,5-DBCat) oxidation, showing the catalytic effects in the order of [CuCl₂L₂]·2H₂O > [CuBr₂L₂]·2H₂O > [Cu(H₂O)₂L₂]·(NO₃)₂ > [Cu(ClO₄)₂L₂] > [Cu(BF₄)₂L₂] in chloroform and exhibiting the catalytic effects of only [Cu(H₂O)₂L₂]·(NO₃)₂ in acetone. Thus, the catalytic effect on catechol oxidation is strongly dependent on anions and media.
