Artykuł
Two new coordination network based on mixed ligands, orotic acid potassium salt with 1,3-Di(4-pyridyl)propane (dpp) and malonic acid at room temperature were synthesized as [Cu2(dpp)(HOr)2·2H2O]n (1) and [Cu(HOr)(H2O)2]n (2) respectively. To strategically design and synthesize Cu(II)-coordination networks where N H⋯O and OH⋯O hydrogen bonds act as connecting tools in the construction of three dimensional networks have been discussed. The both complexes have been characterized by single crystal X-ray analysis, elemental analysis, magneto-structural study along with EPR study. The magnetic data reveals that the complex 1 shows antiferromagnetic exchange interactions while complex 2 shows ferromagnetic exchange interaction through {⋯HNCO} dimer. The DFT calculation and HOMO/LUMO molecular orbitals analysis is used to rationalized the magnetic behavior in these coordination polymers.
