设计并合成了一个含吡啶基团的柔性配体:N,N’-Bis(3-pyridylmethyl)-1,4-benzenedimethylamine(bpb)。通过bpb与硫酸锌及硫酸铜反应得到了两个新型具有一维链状结构的配位聚合物:犤M(H2bpb)(H2O)4犦(SO4)2·6H2O犤M=Zn?1,Cu?2犦。X-射线晶体结构测定表明,这两个化合物均属三斜晶系,并具有相同的空间群P1珔,晶体学参数分别为配合物1:a=11.8055(12)?,b=11.8778(12)?,c=12.1840(13)?,α=80.763(2)°,β=71.982(2)°,γ=80.913(2)°;配合物2:a=11.7403(19)?,b=11.890(2)?,c=12.254(2)?,α=71.339(3)°,β=81.936(4)°,γ=80.917(4)°。
A flexible ligand containing pyridine group was designed and synthesized: N, N’-Bis (3-pyridylmethyl) -1,4-benzenedimethylamine (bpb). By the reaction of bpb with zinc sulfate and copper sulfate, two novel coordination polymers with one-dimensional chain structure were obtained: M (H2bpb) (H2O) 4 (SO4) 2 · 6H2O 犤 M = Zn 1 1 ? 2 犦. The results of X-ray crystallography show that the two compounds belong to the triclinic system and have the same space group P1 晶. The crystallographic parameters are as follows: a = 11.8055 (12),, b = 11.8778 (12) , α = 80.763 (2) °, β = 71.982 (2) °, γ = 80.913 (2) °; complex 2: a = 11.7403 (19) ?, b = 11.890 (2) ?, c = 12.254 (2)?,? = 71.339 (3) °,? = 81.936 (4) °,? = 80.917 (4) °.
