Self-assembly of CuX 2 with C 3 -symmetric tridentate ligand, 1,3,5-tris(nicotinoyloxy-methyl)benzene (L), affords thermodynamically stable C 2 -symmetric metallacyclodimers, [Cu 2 X 2 L 2 (H 2 O) 2 ]X 2 (H 2 O) 2 (X − = NO 3 − , BF 4 − , and ClO 4 − ) in high yields. These cyclodimeric species show the significant anion effects on the catechol oxidation catalysis in chloroform in the order [Cu 2 (NO 3 ) 2 L 2 (H 2 O) 2 ](NO 3 ) 2 (H 2 O) 2 > [Cu 2 (BF 4 ) 2 L 2 (H 2 O) 2 ](BF 4 ) 2 (H 2 O) 2 > [Cu 2 (ClO 4 ) 2 L 2 (H 2 O) 2 ](ClO 4 ) 2 (H 2 O) 2 .

深入了解阴离子对儿茶酚氧化催化的影响：含有 1,3,5-三（烟酰氧基-甲基）苯的环二聚 Cu(II) 配合物

CuX 2 与 C 3 对称三齿配体 1,3,5-三（烟酰氧基-甲基）苯 (L) 的自组装提供热力学稳定的 C 2 对称金属环二聚体 [Cu 2 X 2 L 2 (H 2 O) 2 ]X 2 (H 2 O) 2 (X - = NO 3 - 、BF 4 - 和ClO 4 - ) 收率高。这些环二聚体对氯仿中儿茶酚的氧化催化作用显示出显着的阴离子作用，顺序为 [Cu 2 (NO 3 ) 2 L 2 (H 2 O) 2 ](NO 3 ) 2 (H 2 O) 2 > [Cu 2 (BF 4 ) 2 L 2 (H 2 O) 2 ](BF 4 ) 2 (H 2 O) 2 > [Cu 2 (ClO 4 ) 2 L 2 (H 2 O) 2 ](ClO 4 ) 2 (H 2 O) 2 .
