Abstract

The reaction of CuX2 (X− = ClO4− and BF4−) with a new 1,3,5-tris(isonicotinoyloxymethyl)benzene (L) ligand gives rise to 3D coordination networks, [Cu3L4(CH3CN)6](X)6, with a new topology of the Schläfli point symbol {4•82}4{42•82•102}2{84•122}. [Cu3L4(CH3CN)6](ClO4)6 and [Cu3L4(CH3CN)6](BF4)6 networks have useful oval-shaped pores of 11.2 × 11.2 × 24.8 Å3 and 11.1 × 11.1 × 24.4 Å3 dimensions, respectively. These porous coordination net-works act as good heterogeneous catalysts, oxidizing the catechols in the order 3,5-di-tert-butylcatechol (3,5-DBuCat) > 4-tert-butylcatechol (4-BuCat) > 4-chlorocatechol (4-ClCat). The catalytic effect of [Cu3L4(CH3CN)6](BF4)6 is slightly higher than that of [Cu3L4(CH3CN)6](ClO4)6. The pores of the 3D networks reversibly adsorb the solvents in the order chloroform > tetrahydrofuran > acetone.
