Identify chelate

Postby Chem_Mod » Tue Aug 30, 2011 4:41 pm

1) How do we identify a chelate / chelating complex. The definition states it forms a ring around the central transition atom, but don't all complexes form a ring around the central atom since all the ligands are connected to the central atom. Do the ligands bind to each other to form this "ring"?

2) How do we know if a complex has a bidentate ligand or if it is just a monodentate ligand with a complex?

Chelate refers to a ring like structure involving a transition metal and a ligand. These ring like structures usually result from a polydentate ligand binding the same transition metal. A bidentate ligand is a ligand has two sites available for coordination bonding.

What is the threshold for the bond angle of a chelating molecule? I have heard the term "spacer atom" but am not sure how this relates to whether a molecule can chelate.
