چکیده انگلیسی
The synthesis, X-ray structure, spectroscopic properties, magnetic study and EPR of a chain-type formato-bridged Cu(II) compound, [Cu(dpyam)(μ-O2CH)(H2O)]n(NO3)n (1) is described. The geometry of the copper(II) ion is distorted square pyramidal with a basal plane consisting of two nitrogen atoms of the dpyam ligand and two oxygen atoms of two different formato ligands. A coordinated water molecule occupies the axial position at a distance of 2.222(3) Ã
. The copper atoms are bridged unsymmetrically by a formato anion in a syn-anti arrangement, resulting in a polymeric zig-zag chain structure. The magnetic susceptibility measurements (5-280Â K) agree with a very weak ferromagnetic chain interaction between the Cu centres with a J value of 0.75 cmâ1.
