Artykuł
The novel ternary complex [Cu(hipp)2(bim)2]·PrOH·0.25H2O (1) has been prepared and fully characterised by single crystal X-ray structure determination. The central copper(II) is coordinated by two O-donor atoms of the hippurate ions and by two N-atoms of the benzimidazole ligand with a tetrahedrally distorted square-planar geometry. The complex molecules, connected by hydrogen bonds into a 2D network, form a supramolecular structure. A theoretical DFT calculation performed by the UB3LYP method combined with the LanL2DZ basis set shows that all metal-ligand bonds are of the L → M type. The results of the spectroscopic, EPR and NIR–Vis–UV, as well as magnetic study are consistent with the structural data.
