WebDec 7, 2024 · This reflects delocalization of negative charge within the bidentate deprotonated thiourea ligand. As Martin pointed out, the reasons for the observed denticity are not always transparent. Simply put, it seems like in this case in order to be a bidentate ligand, thiourea molecule needs to increase its nucleophilicity and remove steric … WebDec 6, 2024 · Re: denticity. Postby Riya Sawhney 1C » Mon Dec 06, 2024 12:46 am. Denticity refers to the number of bonds a single ligand can form with a central atom.For example, EDTA, shown below, is hexadentate, meaning it can form 6 bonds. Sigma bonds can rotate, and so parts of the molecule can rotate into the correct position.

Denticity can be defined as the number of atoms in a single ligand that connect to a central atom. It has been observed that in multiple scenarios, just one atom in the ligand links to the metal, leading in a monodentate ligand with a denticity of one. More than one atom is bonded in polydentate or multidentate ligands.
