ABSTRACT:
Single crystals of hexaaquocopper(II)picrylsulphonate tetrahydrate, [Cu(H2O)6(picsul)2.4H2O and the corresponding copper(II) doped zinc and cadmium analogues have been prepared and subjected to EPR studies. X-ray diffraction studies of the pure complex reveal the structure to be triclinic and z=1, with a two dimensional Cu-picsul-Cu-picsul- chain running along b-axis, super exchange interactions are taking place through the chains, linked by H-bonds from uncoordinated water. The line width and line shape analysis indicate the system to be a quasi two dimensional one. A probe into the study of the metal ligand bonding has also been made.
KEYWORDS:
Electron paramagnetic resonance, metal ligand, line width, line shape.
