This work presents a serials of six metal(II) complexes assembled from dual linkers, i.e. previously unutilized semirigid 3-(4-carboxyphenyl)propionic acid (H(2)cpp) and dipyridyl type molecules di(4-pyridyl)ethylene (bpe) or 1,2-bi(4-pyridyl)ethane (bpa). Single crystal X-ray diffraction reveals a diversity of the structures: with compound {[Cu(Hcpp)(2)(bpe)]center dot 2H(2)O}(n) (1) manifesting a metal-organic coordination chain with parallel pendent arms, {[Cu(2)(cpp)(2)(bpe)(2)(H(2)O)]center dot 4H(2)O}(n) (2) displaying a three-fold interpenetrating (4,4) grid, {[Ni(cpp)(bpe)(1.5)H(2)O]}(n) (3) featuring a self-interpenetrating metal-organic coordination framework, {[Ni(Hcpp)(2)(bpa)(2)(H(2)O)(2)]}(n) (4) exhibiting a metal-organic coordination chain with vertical pendent arms, {[Co(Hcpp)(2)(bpa)(2)(H(2)O)(4)}(n) (5) affording a metal-organic coordination linear chain, and {[Co(2)(cpp)(2)(bpa)(1.5)H(2)O]}(n) (6) affording a metal-organic coordination framework with pillared layers. It is shown that the semirigid carboxyphenylpropionate bears diverse metal-organic frameworks (MOFs) with low porosity resulting from the penetration of coordination networks. Magnetic measurement reveals that 6 presents weakly antiferromagnetic behavior.
