Question

Explain the coordinate chemistry of Cu and it’s tetravalent nature as well as how different Ligands including functional groups like methoxy and carboxilic acid bond with the Lewis acid

Answer 1

We can define the coordination number as the number of electronic pairs that accept a Lewis acid (usually a metal center), that is, if a coordination compound has two species that are donating electron pairs, then it will have a number of coordination 2. The coordination number of a complex is influenced by the relative sizes of the metal ion and the ligands, as well as the electronic factors, which will change depending on the electronic configuration of the metal ion.

Copper (Cu) can have different coordination numbers, one for each state of oxidation present, for Cu (I) coordination number 1, for Cu (II) coordination number 2, for Cu (III) coordination number 3 and for Cu (IV) coordination number 4. This is, that the coordination number determines the amount of atoms that can be attached to that atom or Cu ion.

Metal ions can function as Lewis acids and form covalent bonds with various molecules and ions that act as Lewis bases, we have found many examples of Compounds product of this class of interactions, copper is one of these compounds.
