Coordination Compounds

Front

What are the two types of linkages shown by metals in coordination compounds?

Back

Primary and secondary valences.

Front

What are primary valences in coordination compounds?

Back

Primary valences are normally ionisable and are satisfied by negative ions.

Front

What are secondary valences in coordination compounds?

Back

Secondary valences are non-ionisable and are satisfied by neutral molecules or negative ions.

Front

What is the relationship between secondary valence and coordination number?

Back

The secondary valence is equal to the coordination number and is fixed for a metal.

Front

What determines the spatial arrangements of ions/groups bound by secondary linkages in coordination compounds?

Back

The characteristic spatial arrangements correspond to different coordination numbers.

Front

What is the significance of chelation in coordination chemistry?

Back

Chelation enhances the stability of metal complexes by forming multiple bonds between a ligand and a metal ion.
