Synthesis and crystal structure of a novel coordination polymer: {[Zn₂(6-Pydc)₂(Bpp)₂] · 4H₂O}n

A 1D zigzag coordination polymer {[Zn-2(2,6-Pydc)(2)(Bpp)(2)] center dot 4H(2)O}(n) (I) [2,6-H(2)Pydc = 2,6-pyridinedicarboxylic acid, Bpp = 1,3-bis(4-pyridyl)propane] has been synthesized via the hydrothermal method. Single crystal structural analysis exhibits that a novel 2D complicated framework comprised of two kinds of infinite 1D zigzag chains was stabilized by chains through hydrogen bonding, and pi-pi stacking interaction, which aggregate together to give birth to the 3D network structure via the C-H ... O interaction.
