Interwoven coordination polymers sustained by tautomeric forms of the bridging ligand

Abstract

Supramolecular interwoven double chains are found in two isomeric zinc thiolate complexes which differ in terms of the tautomeric forms of the bridging ligands, i.e. 3-NC5H4CH2N(H)C([double bond, length as m-dash]O)C([double bond, length as m-dash]O)N(H)CH2C5H4N-3 or 3-NC5H4CH2N[double bond, length as m-dash]C(OH)C(OH)[double bond, length as m-dash]NCH2C5H4N-3. In each case, the bridging ligands are threaded through 28-membered rings mediated by O–H⋯O hydrogen bonding. Hydrogen bonding interactions between the rings and threading molecules, i.e. O–H⋯Ocarbonyl or O–H⋯Nimine, are dependent on the tautomeric form of the threading molecules.
