      Two novel metal-organic coordination polymers $ [Cu_{2}(bpp)Cl_{2}]$ (1) and $[Cu_{2}(bpp)_{2}SO_{4}]$·DMF·$3H_{2}O (2) were prepared from the reactions of 1,3-bis(4-pyridyl)propane (bpp) with $CuCl_{2}$ and $CuSO_{4}$,respectively, which were characterized by single-crystal X-ray diffraction analysis, elemental analysis, IRspectroscopy and powder X-ray diffraction analysis. 1 features inorganic one-dimensional $ [Cu_{2}Cl_{2}]$ ribbons,which are linked by the bpp ligands to form a three-dimensional metal-organic framework exhibiting a 3,3,4-connected 3-nodal topology. 2 presents $[Cu_{2}SO_{4}]$ inorganic dinuclear secondary building blocks which are furtherconnected by the bpp ligands to construct a two-dimensional framework featuring flask-stacking appearance.They are typical examples of metal-organic framework constructed by the synergistic use of organic andinorganic linkers.

      The reactions of 2-amino-2-methyl-1-propanol (MepH) with Co(ClO₄) ₂•6H₂O in the presence of acetic acid gave [Co₂ (Mep) ₃ (OAc)(MepH)](ClO₄) ₂•MepH (1) and [CoIII ₄ CoII ₂ (Mep)8(μ₃-OH) ₂ (OAc) ₄](ClO₄) ₂• 2EtOH•2H₂O (2). They were characterized by elemental analysis, IR and single crystal X-ray diffraction analysis. Compound 1 presents a dinuclear structure with its two Co atoms linked by two Mep⁻ ligands and one acetate ligand. The two Co(II) and four Co(III) centers in 2 are held together by eight Mep⁻ ligands, two μ₃-OH⁻ ions and four acetate ligands to form a hexanuclear skeleton which contains a defected face-shared dicubane core. Their discrete polynuclear units are further linked into double-layered and mono-layered two-dimensional H-bonded framework, respectively.
