摘要
A new Chromium(Ⅲ) complex, [Cr(Hcah)(H2O)2]·2H2O, where H4cah=2-[N,N-bis(carboxymethyl)aminome-thyl] hydroquinone (H4cah), has been synthesized and characterized using X-ray diffraction single crystal structure determination, IR and elemental analysis. The complex belongs monoclinic, space group P21/c, with a=0.792 05(4) nm, b=1.008 63(6) nm, c=1.920 40(10) nm, β=93.069(4)°, V=1.531 98(14) nm3, and Z=4. The cyclic voltametric analysis shows that the electron transfer in the electrode reaction is irreversible for Cr(Ⅲ)/Cr2O72-and Cr(Ⅲ)/Cr(Ⅱ) redox couples while reversible for process of interchange from p-Hydroquinone to p-semiquinones. CCDC: 666208.

The complex belongs monoclinic, space group P21/c, with a=0.792 05 （4） nm, b=1.008 63（6） nm, c=1.920 40（10） nm, β=93.069（4）°, V=1.531 98（14） nm^3, and Z=4. The cyclic voltametric analysis shows that the electron transfer in the electrode reaction is irreversible for Cr（Ⅲ）/Cr2O7^2- and Cr（Ⅲ）/Cr（Ⅱ） redox couples while reversible for process of interchange from p-Hydroquinone to p-semiquinones.
