    • - 3, 1.83 < θ < 25.06, F(000) = 7113. Data collection T = 293(2) K, of 44905 reflections measured (- 26 ≤ h ≤ 23, - 16 ≤ k ≤ 16, - 29 ≤ l ≤ 29), 13342 [R(int) = 0.0418] independent reflections were used to solve the structure. Based on these data, final R1 = 0.0547 (all data), wR2 = 0.0949, and the goodness-of-fit on F2 is 1.060. The X-ray diffraction data were collected on a Bruker Smart 1000 CCD diffractometer with Mo Kα (λ = 0.71069 Å) by ω and θ scan mode at 293 K. The structure was solved by direct method and refined on F2 by full-matrix least-squares technique using the SHELXTL-package [13]. All non-hydrogen atoms were refined anisotropically. The positions of hydrogen atoms on carbon atoms were calculated theoretically.

    • Electrochemical measurements were performed with a CHI 440 electrochemical workstation connected to a Digital-586 personal computer. A conventional three-electrode cell was used at room temperature. The modified electrode was used as working electrode. A SCE and a platinum wire were used as reference and auxiliary electrodes, respectively. Complex 1 bulk-modified carbon paste electrode (1-CPE) was fabricated as follows: 500 mg of graphite powder and 30 mg of 1 were mixed and ground together by an agate mortar and pestle to achieve a uniform mixture, and then 0.15 mL of Nujol was added with stirring. The homogenized mixture was packed into a glass tube with a 3 mm inner diameter, and the tube surface was wiped with weighing paper. Electrical contact was established with a copper rod through the back of the electrode. The same procedure was used for preparation of bare CPE without compound 1.
