Two new coordination compounds {(bpyH2)·[Fe(bpy)2(H2O)2(SO4)2]·2(H2O)}n (1) and {[Cu(bpp)2(H2O)]·(BF4)2·dmf·0.75(H2O)}n (2), (where, bpy= 4,4'-bipyridine and bpp= 1,3-bis(4-pyridyl)propane, dmf= N,N-dimethylformamide) have been synthesized by slow evaporation method based on rigid and flexible bis(pyridine) ligands. The obtained compounds were characterized by thermal analysis, FT-IR spectroscopy and single crystal X-ray diffraction analysis. The structure of 1 is a channel-containing open framework constructed through the hydrogen-bonding supported by the criss-cross arrangement of the 1D Fe-bpy anionic chains, in which the surrounding of the metal atom is completed by oxygen atoms belonging to water molecules and SO42- anions. The structure of 2 is formed by a one-dimensional polymeric cationic chain, in which the four bpp ligands connect with Cu(II) by four nitrogen atoms and one oxygen atom that belongs to a molecule of water that completes the surrounding of each metal atom. The complexes crystallize in the monoclinic space groups C2/c and P21 respectively, where Fe(II) and Cu(II) ions present a N2O4 octahedral and N4O square pyramidal environment. The hydrophilic regions absorb bpyH22+ and water molecules in 1 and BF4- anions, water and dmf molecules in 2, which are held in the crystal lattices via hydrogen bonds.
