| 摘要: | Polarographic reduction half=wave potentials for the series of inorganic complexes M(RC5H4N)2Cl2 (M=Co(II), Ni(II)m Cu(II), Zn(II), Cd(II); R=H, CH3, NH2, OH, CONH2, CHO, COCH3, COPh, Cl, Br and CH2OH) are reported to show the substituent effects in these complexes. consequently, the E1/2 values correlated linearly with Hammett substituent parameters, the slope of the E1/2 vs σ plots evidently decreases in order of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II). |
