Structural Transformation of Zn -Dipyridylamide-Based Coordination Frameworks: Hybrid-Ligand and Metal Effects.

A series of one-dimensional (1D) double-zigzag ({[Zn(papx) (H O) ](ClO ) } (x=so 1, sc 3, oc 5, and soc 7) and 2D polyrotaxane ([Zn(papx) (ClO ) ] (x=so 2, sc 4, oc 6, and soc 8) frameworks are synthesized by the reactions of Zn(ClO ) with equimolar amounts of papx (i.e., papso=1/2paps+1/2papo, papsc=1/2paps+1/2papc, papoc=1/2papo+1/2papc, and papsoc=1/3paps+1/3papo+1/3papc; paps=N,N'-bis(pyridylcarbonyl)-4,4'-diaminodiphenyl thioether, papo=N,N'-bis(pyridylcarbonyl)-4,4'-diaminodiphenyl ether, papc=N,N'-(methylenedi-p-phenylene)bispyridine-4-carboxamide).
