From 1D zigzag chain to 1D tubular structure, weak field ligand-dependent assembly of cucurbit[6]uril-based tubular coordination polymer.
The reaction of cucurbit[6]uril with Cu(NO3)2 and CuCl2, respectively, generates a 1D zigzag chain of {[Cu(H2O)4(cucurbit[6]uril)].(NO3)2.(H2O)8}n and a 1D tubular structure of {[Cu(H2O)2(Cl)2(cucurbit[6]uril)](1/3).(H2O)3}n, showing clearly how to control the reversible and mutual interconnections between ligand and metal ion under the guide of coordination chemistry.
