Abstract
The reactions of K-3[Cu(CN)(4)} with aliphatic diamines [urea, ethylenediamine (en) and propane-1,3-diamine (tn)] in presence of Me3SnCl or Ph3SnCl form coordination polymers (CP) with various compositions and architectures. Five coordination polymers; Ph3SnOH, 1, , 2, , 3, , 4 and K[Cu (2) (I) (CN)(3)]center dot(H2O), 5, have been characterized by elemental analyses, IR, mass and H-1-NMR spectroscopy, thermogravimetric analyses and X-ray single crystal diffraction. The structures of CP 2-5 are organotin free and depend on the type of the solvent and the structural variability and flexibility of the R3Sn cation and aliphatic diamine ligand. The structures contain different building blocks; [Cu-2(CN)(4)], [Cu-2(CN)(3)] and [Cu-2(CN)(3)](2).
