How do we know if something can form a chelating complex like in 9C7?

Something can form a chelating complex if it has a) more than one lone pair available for bonding (bidentate or polydentate) AND b) has those bonds close enough together to form a ring (i.e. they are on the same side of the molecule). A molecule that can form a chelating complex should have the structure
(lone pair) - (spacer atom) - (spacer atom) - (lone pair). It is important that the atoms with lone pairs are attached via sigma bond so that they can rotate to bond to the same transition metal.
