Cu2(μ-dppb)2(μ-Cl)2的合成、晶体结构及非线性光学性质

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.

吡唑桥联双核钯(Ⅱ)配合物的合成和结构研究

金属引导的多功能杂环配体配位形式的超分子自组装体系的研究已经发展成为一个非常活跃的研究方向[1￣4]。吡唑作为桥联配体用于组装环状超分子结构的报道很多,主要集中在直线型的一价Ag"、Au"、Co"、Cu"等[5,6]以及二价Ni!、Cu!、Co!、Zn!、Cd!、Fe!等[7￣9],但是与二价Pd![10￣12]和Pt![13￣15]的组装的报道较少。由于Pd!和Pt!通过吡唑桥联后,会产生较强的金属-金属相互作用,因而产生一些新颖的物理和化学性能[11,15]。在已知文献报道中[11,14,15],吡唑上的N-H质子都要在强碱的作用下才能去除,然后以桥联形式同金属配位,并且所得环…
