Variable temperature (4. 0 - 30 0 K ) magnetic susceptibility data for the complexes show that there exists the antiferromagnetic exchange interaction between the two copper( ) ionswith J(cm-1 ) valuesof- 0 .4 6 2 (1)、- 1.0 3 (2 ) and - 6 .86 (3) . The preliminary study of the electrochemical characteristicsof complex (3) was also carried out.展开更多
A new complex with binuclear nickel(Ⅱ) complex [Ni2(bbimp)(CH3CH2OH)2Cl2]Cl· 4H2O (bbimp=2,6 bis[bis(2 benzimidazolylmethyl)]aminomethyl 4 methylpheno)(o)had been synthesized and characterized by elementary anal...A new complex with binuclear nickel(Ⅱ) complex [Ni2(bbimp)(CH3CH2OH)2Cl2]Cl· 4H2O (bbimp=2,6 bis[bis(2 benzimidazolylmethyl)]aminomethyl 4 methylpheno)(o)had been synthesized and characterized by elementary analysis, IR and UV. The molecular structure of the title complex was determined by X ray single crystal diffraction method. The crystal is monoclinic, space group P21/n with a=20.803(2)? , b=30.708(3)? , c=20.959(2)? , β =105.776(2)° , Z=8, V=12885(2)? 3, Dx=1.132Mg· m- 3, μ =0.755mm- 1, F(000)=4592, R1=0.1267, S=1.376. It was showed that the nickel? cation is the central ion of a distorted octahedral coordination with two N belonging to benzimidazole, a bridging phenolate O, a N of tertiary amine, a Cl anion, and an O of an ethanol molecule. Two nickel? cations in a molecular structure had the same coordinated environment. CCDC: 197601.展开更多
