Abstract

Two templated borates, [Co(bpy)₂BO₂(OH)]·[B₅O₆(OH)₄]·H₃BO₃·H₃O·H₂O (1) and [Cu(bpy)(OH)]₂·[B₅O₆(OH)₄]₂·H₂O (2), have been synthesized successfully and characterized by single-crystal X-ray diffraction, powder X-ray diffraction, and Fourier transform infrared. The [Co(bpy)₂BO₂(OH)] complex in 1 shows a very rare coordination mode between Co²⁺ and BO₂(OH)^2-. The structures of 1 and 2 can be adjusted by changing the reagent. The oxygen reduction reaction activity of these Co- and Cu-based catalysts was studied. The E_1/2 values of Co-C-750 and Cu-C-750 are 0.864 and 0.837 V, respectively.
