Simultaneous encapsulation of an infinite T4(0)A(0)6(0) water tape and discrete water hexamers in a hydrogen-bonded Ag(i) supramolecular framework

Abstract

Self-assembly of Ag₂O, 1,4-bis(pyrid-4-yl)benzene (dpb) and 1,3-benzenedicarboxylic acid (H₂bdc) resulted in a one-dimensional mixed-ligand Ag(I) coordination polymer [Ag₂(dpb)₂(bdc)·9H₂O]_n (1), in which infinite 1D T4(0)A(0)6(0) water tapes and discrete water hexamers were simultaneously encapsulated. Chair-like water hexamers and D_2h water tetramers with two dangling water molecules were alternately hydrogen-bonded into the unprecedented 1D T4(0)A(0)6(0) water tape. Additionally, results on the thermal stability, UV-Vis absorption and photoluminescence spectra of 1 were discussed.
