Abstract

Spectroscopic studies of newly synthesized coordination polymers of the type [CuxFey(dedb)·2H2O]n {where dedb Combining double low line dianion of 2,5-dichloro-3,6-bis(ethylamino)-1,4-benzoquinone (1); x Combining double low line 1, y Combining double low line 0 (2); 0, 0.67 (3); 0.5, 0.33 (4); 0.25, 0.5 (5); 0.125, 0.583 (6); 0.0625, 0.625 (7) and n Combining double low line degree of polymerization} have been carried out by IR, Mössbauer and electron paramagnetic resonance (EPR) spectroscopic techniques. Powder X-ray diffraction studies reveal the crystalline nature of the polymers. Mössbauer and EPR spectroscopic studies and variable temperature susceptibility measurements indicate the presence of high spin Fe(III) (S Combining double low line 5/2) in the polymers. A rare coexistence of ferromagnetism and electrical conductivity observed is discussed under present communication.
