Abstract

A hydro(solvo)thermal reaction between Zn(ClO4)2·6H2O and Z-3-(4-cyanostyryl)pyridine affords an unprecedented chiral 3D coordination polymer Zn{Z-[4-2-(3-pyridyl)ethenyl]benzoate}2·0.5H2O with two intersecting six-fold helices, which shows a modest SHG activity owing to the essentially non-conjugate nature of the bridging ligand.

Z-3-(4-cyanostyryl)pyridine was prepared in 27% yield by a room-temperature Wittig reaction between (4-cyanobenzyl)triphenylphosphonium bromide and 3-pyridinecarboxaldehyde with NaOH as the base in dichloromethane. The product was purified by silica gel column chromatography [hexane–ethyl acetate (1∶1)].
