在水热条件下合成了一个新颖的配位聚合物[Cd(nip)(bix)_(0.5)H_2O]n (1) (nip=5-硝基间苯二甲酸,bix=1, 4-(亚甲基)二咪唑).单晶X-射线衍射分析表明,晶体属二斜晶系,P1空间群,晶胞参数a=0.827 1(2) nm,b=1.0165(3) nm,c=1.1474(3) nm,α=70.862(4)°,β=68.988(4)°,γ=69.001(4)°,γ=0.8184(4)nm~3 , Z=2 , D_c=1.861g·cm~3,μ=1.380 mm~(-1)F(000)=454 ,最终的R1=0.0400, wR2=0.0901.配合物1中,nip~(2-)离子以μ3桥联的方式连接Cd(Ⅱ)中心形成含有交替8元环和16元环的一维聚合链,进而,bix配体柱撑一维链形成了(3,4)-连接的二维配位网;最后,通过R_2~2(6)氢键环的作用,二维网拓展为具有(3,5,5)-连接(3.4.5)(3.4~2.5.6~4.7.8)(3.4~3.5~2.6~2.7~2)拓扑结构的三维超分子体系.此外,本文还研究了配合物1的热稳定性和荧光性质.

A novel compound [Cd (nip) (bix)o,5H20]n (1) (nip =5-nitroisophthalic acid and bix=1,4-bis (imidazol-l-ylmethyl)-benzene) has been hydrothermally prepared and characterized. Single-crystal X-ray diffraction studies indicate that the compound 1 crystallizes in triclinic, space group PI with a=0.8271(2) nm, b=1.0165(3) nm, c=1.147 4(3) nm, α=70.862(4)°,β=68.988(4)°,γ=69.001(4)°,γ=0.8184(4)nm~3 , Z=2 , D_c=1.861g·cm~3,μ=1.380 mm~(-1)F(000)=454 , and final R,=0.040 0, wR2=0.090 1. In 1, nip' ions act as ,u.3-linker to bridge Cd n atoms into an infinite 1D chain with alternately 8-member ring and 16-member ring, moreover, the bix ligands pillar these 1D chains into 2D (3,4)-connected coordination network. Eventually, through R22(6) H-bonding rings, these 2D nets are extended to 3D supramolecular framework showing a new (3,5,5)-connected (3.4.5) (3.4~2.5.6~4.7.8){3.4~3.5~2.6~2.7~2}topology. In addition, the thermal and fluorescence properties associated with the compound 1 were also investigated.
