Controllable assembly of a three-dimensional metal-organic supra­molecular framework displaying hydrogen-bonding and [pi]-[pi] stacking inter­actions

A one-dimensional double-chain zinc(II) complex with phthalate and 2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]acetate (PPAA^-) ligands has been prepared by solvothermal reaction of 2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]aceto­nitrile (PPAN) with zinc(II), the PPAN being hydrolyzed to PPAA^-. The one-dimensional double chains are extended into a three-dimensional supra­molecular architecture via hydrogen-bonding and [pi]-[pi] stacking inter­actions.
