Abstract:

The mu2-bridging bidentate coordination modes of the crystallographically unique phthalate ligands in piperazinediium bis(mu2-phthalato)zincate(II) monohydrate (1) result in Zn...Zn separations of 5.839(5) and 8.142(3) Angstrom respectively leading to a one-dimensional Zn(II) ladder. The organic cation, ladder complex anion and lattice water in (pipH2)[Zn(pt)2].H2O (1) (pipH2= piperazinediium, pt = phthalate) assemble into a unique supramolecular network, resulting in the following H-bonded sequence, vis., water...cation...water...ladder...water in the crystallographic ac plane.
