2D entanglement of 1D flexible zigzag coordination polymers leading to an interwoven network

A 1D flexible zigzag coordination polymer, {[Zn(bac)2(bpp)] · 1.5H2O}n (1) (bac = 1-benzoylacetone, bpp = 1,3-bis(4-pyridyl)propane), has been synthesized by ambient evaporation of mixed solution and structurally characterized by single crystal X-ray diffraction. The zigzag chains in two different directions are entangled to generate a 2D interwoven network, which is stabilized by hydrogen bonding interactions. The powder X-ray diffraction (XRD) and thermogravimetric analysis (TGA) of 1 have also been studied.
