合成了N-苯基-1,7-二硒杂-4-氮杂-[7]二茂铁环蕃(1),并用核磁、质谱、单晶X-射线衍射进行了表征。晶体结构测试结果表明1是属于正交晶系的Ibca空间群,晶胞参数a=0.954 74(2)nm,b=0.959 58(2)nm,c=7.859 0(2)nm,其中晶胞参数c值很长,这种现象在N-Se杂大环中很少见。光谱研究显示1仅对Hg2+和Cu2+的加入产生响应,表现为紫外最大吸收峰的红移和荧光淬灭。 相似文献

The complex Cu2(μ-dppb)2(μ-Cl)2 has been synthesized from the reaction of CuCl, dppb and (n-Bu)4NCl. The crystal belongs to the triclinic with space group P1. The unit cell parameters are: a=9.939(4)?, b=10.083(6)?, c=14.104(5)?, α=76.46(3)°, β=71.02(2)°, γ=70.87(5)°. The single crystal X-ray diffraction analysis reveals that it has a bi-ring structure with a symmetry center at the middle of two Copper atoms. The outer ring is a 14-membered ring of Cu-dppb-Cu-dppb, and the inner ring is a 4-membered ring composed of two Cl- and two Cu(Ⅰ). Investigation of third-order optical nonlinearity shows that it exhibits considerable nonlinear absorptive and self-defocusing effect with α2=1.75×10-13m·W-1 and n2=3.19×10-18m2·W-1.

Amercury(Ⅱ)coordinationpolymerwith1,5,9-triselena[9]ferrocenophane(L),[HgI2L·0.5C4H4O·0.5CH3OH]n, has been synthesized and characterized. The X-ray crystal structure shows that bridging by the ligand L causes compound to form one-dimensional chain. The half-wave potential of 1,1′-ferrocenylene group is more negative than that of the "free" ligand, which reveals no through-space interaction Hg…Fe in the coordination polymers. 相似文献
