A number of metal-EDTA complexes have been reported to have the EDTA acting as a pentadentate ligand (only five sites on EDTA bind, one carboxylic group does NOT). A water molecule or another ligand is in the sixth site, so the complexes are still octahedral in geometry. Is EDTA aRead More →
Oxalate ion is a bidentate ligand even though it contains four O atoms which have lone pairs of electrons. In this complex, two oxalate ions are bonded to the Ni atom. The coordination number of 4 results in a square planar structure. Is EDTA a Unidentate ligand? In most ofRead More →
Water is a common ligand. … An electron pair from the ligand, such as water, provides both of the electrons for the bond that forms between itself and the central metal atom or ion. Here a single ligand L, which could be water, donates a pair of electrons to formRead More →
noun, plural: ligands. (1) A molecule, ion or atom bonded to the central metal atom of a coordination compound. (2) Any substance (e.g. hormone, drug, functional group, etc.) that binds specifically and reversibly to another chemical entity to form a larger complex. What is ligand give two examples?
