The reaction of M(NO_3)_2·6H_2O (M=Cd, Zn), isophthalic acid(H_2IP) as well as 1,4-bis(4-methyl-imidazolyl) benzene(BMIB) results in formation of a 1D complex {[Cd(BMIB)(H_2O)_2](NO_3)_2}_n (1) and 3D complex {[Zn_2(BMIB)_(1.5) (OH)(IP)_(1.5)]·H_2O}_n (2). X-ray diffraction crystal structure analysis shows that 1 crystallizes in triclinic system, space group P1 with a=0.3820 8(3) nm, b=0.904 72(7) nm, c=1.378 29(10) nm, α=98.581(4)°, β=97.020(3)°, γ=94.398(3)°. In 1, BMIB links all the Cd atoms into a 1D chain, which forms 2D bilayer th...

利用过渡金属镉(锌)盐与1,4-二(4-甲基咪唑)苯、间苯二甲酸分别采用分层和水热法合成了化合物{[Cd(BMIB)(H_2O)_2](NO_3)_2}_n(1)和{[Zn_2(BMIB)_(1.5)(OH)(IP)_(1.5)]·H_2O}_n(2)(BMIB=1,4-二(4-甲基咪唑)苯,IP~(2-)=间苯二甲酸根),并对其进行了元素分析、IR及X射线衍射法表征。晶体结构研究表明:配合物1属于三斜晶系,P1空间群。晶胞参数:a=0.382 08(3) nm,b=0.904 72(7) nm, c= 1.378 29(10) nm,α=98.581(4)°, β=97.020(3)°,γ=94.398(3)°。配合物2属于单斜晶系,C2/c空间群。晶胞参数:a=3.764 07(9) nm,b= 1.017 18(5) nm, c=2.015 31(11) nm, β=120.860(2)°。配合物1是由配体BMIB连接...
