Synthesis and Crystal Structure of [Cu2(bpa)2(phen)2(H2O)]2·H2O

A novel neutral molecular square Cu(bpa)(phen)]4 was generated from hydrothermal reactions. Single-crystal X-ray diffraction analysis demonstrates that bpa2- ligands bridge performed molecular Cu(phen)]2+ corners into an interesting molecular square though the corner Cu(phen)]2+ may contain two cis-equatorial and two free axial free coordination sites, which are usually propitious to afford one dimensional zigzag polymer. Moreover, these independent molecular squares are further spontaneous self-assembled into a three-dimensional network due to recognition sites of phen ligands, which characterizes an interesting topological structure and suggests a possible route to understanding the effect of noncovalent interactions in the supramolecular chemistry and biochemistry.
