Abstract
A new 1D-coordination polymer of Cu(II) ions, {(2- apymH)2[Cu(pyzdc)2]·6H2O}n, (2-apym = 2-aminopyrimidine, pyzdcH2 = pyrazine- 2,3-dicarboxylic acid), was synthesized based on the proton transfer mechanism and characterized by elemental analysis, infrared spectroscopy and single crystal X-ray diffraction. The coordination polymer consists of infinite chains of [Cu(pyzdc)2]2- bridged across a double chain running along the a-axis and discrete (2-apymH)+ fragments. The Cu(II) ion is located on the inversion centre in the basal plane of an elongated octahedron with two oxygen atoms from adjacent (pyzdc)2- ligands occupying the axial positions. The interaction between oxygen atoms of water molecules with the dicarboxylic acid plays an important role in the overall supramolecular assembly.
