A novel chiral framework constructed through three-fold interpenetration of (4,4) nets of Ni(II)-muconate-4,4′-bipyridine

A novel three-fold interpenetrated structure in chiral space group, P3121, has been synthesized by hydrothermal method. Crystal structural analysis reveals that both trans,trans-muconic acid and 4,4′-bipyridine act as linear bridges between square-planar nodes Ni(II), with a chiral configuration of 4,4′-bipyridine.
