摘要

Three coordination polymers were prepared by the reaction of a new flexible multimodal ligand,bis-(2-pyrazylmethyl)sulfide(L),with AgX salts(X = BF4- or PF_6~-).The polymers showed an increasing dimensionality from 1-D to 2-D to 3-D,and the influence of solvent and anion on the formation and dimensionality of these coordination polymers was explored.A 1-D twisted ladder-like polymer with eta1-bound benzene and a 2:1 AgPF6-to-L ratio,1·MeCN,was formed when benzene was present in the solvent mix.A 2-D undulating sheet with 4.82 topology and a 1:1 AgPF6-to-L ratio,2,was formed when CH2Cl2 was present in the solvent mix.A 3-D network,3,with two different 4.8~2 nets linked together by 4.85 bridging nodes was formed when a 1:1 AgBF4-to-L ratio was used and MeNO2 was present in the solvent mix.Coordination arrays 2 and 3 were found to be related topologically.
