Özet
The coordination polymer with mixed ligand [Cu2(H2O)2 (pm) (ina)2]n.3nH2O (pm = tetraanion of pyromellitic acid, ina = isonicotinamide) was studied mostly on its supramolecular architecture. Single crystals were synthesized and structural properties of the 1D polymer were characterized by Single Crystal X-ray diffraction (SCXRD), different spectroscopic methods (Infrared (IR) spectroscopy, UV--Vis spectroscopy and EPR spectroscopy), Thermal and Elemental analysis. It has been observed that complex has crystallized in the monoclinic space group P21/c. The geometric environment of Cu(II) ion is five-coordinated in slightly distorted square pyramidal geometry and τ value have found 0.13. The pyromellitate ligands connecting the metal centers act as bridge and form 1D polymer chains of 2,4 ribbon type [1]. The ladder-like polymer is connected by Osingle bondH⋯O and Nsingle bondH⋯O hydrogen bonds ...
