Özet:

 

A compound (1), [H2-(4,4'-bipy)]2+[(Cr2O7)]2- and a  metal organic-inorganic coordination framework (2),  [Mn(4,4'-bipy)(Cr2O77)(H2O)2] (4,4'-bipy=4,4' -bipyridine) were  successfully synthesized by microwave method.  Their characterization  was performed by single crystal X-ray crystallography and FT-IR  spectroscopy.  The crystal structure of 1 revealed a diprotonated  4,4'-bipyridium dichromate compound while compound 2 is an  onedimensional (1D) polymer in which (Cr2O7)2- acts as a bridging  ligand supporting the formation of infinite {[Mn(4,4'-bipy)(Cr2O7)(H2O)2]}n  polymeric chains.  The geometry of the 4,4'-bipy ring in 1 is typical  coplanar, but twists in 2.  In the free molecule 1, dichromate ligand  adopts an eclipsed conformation, but adopts a staggered conformation  in complex.  The principal features of the crystal supramolecularity  of 1 and 2 are non-covalent weak interactions which occurred via  N-H...O and C-H...O hydrogen bonding.
