Solvothermal synthesis of an achiral ligand N,N-bis(3-pyridyl) isophthalamide (bpip) with ZnSO4 under 120 °C yield a novel compound, [Zn(bpip)SO4]n, which displays chiral self-assembly into an infinite double-stranded helical coordination polymer consisting of two single-stranded helices with the same P handedness. These chiral infinite double-stranded helical chains are further interwoven by the 1D Zn–SO4–Zn chains to form a novel 3D framework structure with a rare 65.10 topology. On the basis of the results of TG-DSC analyses, the structure is thermally stable up to ~ 467.4 °C.
A highly stable 3D chiral coordination polymer consisting of two single-stranded helices with the same P handedness based on achiral ligand bpip is reported here. These chiral infinite double-stranded helical chains are interwoven with 1D S–O–Zn–O–S chains forming a 3D framework structure with novel 65.10 topology.Figure optionsDownload as PowerPoint slideHighlights
