摘要

A new 3-D copper(II) complex, formulated as [Cu_2(2,bbt ect(=e 1bec]n))ze( ne_e[n-1H,)2_,4_,n5-4 tetracarboxylate, and en = ethylenediamine], was hydrothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, and single crystal X-ray diffraction. The structural analysis of 1 reveals that copper(II) connect by μ-bridging b_tec to 6form a 3-D cordination polymer, in which four carboxylates of btec show monodentate and bidentate coordination. Complex 1 was used as solid bulkmodifier to fabricate renewable carbon paste electrode (1-CPE) by direct mixing method. The cyclic voltammogram of 1 -CPE displayed one-electron quasi-reversible redox waves in potential range 300 to —300 mV due to Cu(II)/Cu(I). Moreover, 1-CPE showed electrocatalytic activity toward the reduction of nitrite.
