COORDINATION COMPOUNDS: * FLEXIDENTATE CHARACTER OF POLYDENTATE LIGANDS; * Poly dentate ligands have flexi dentate character in the sense that all donors atoms may not form coordinate bonds with the central metal atom or ion. For example; EDTA which is the hexa dentate ligand also acts as tetra dentate or penta dentate in certain complexes. Similarly sulphate ion‚ which is a bi dentate ligand‚ also acts as a mono dentate ligand in certain complexes‚ e.g. in [Co(SO4)(NH3)5]Cl. * LABILE
