4,4'-Bipyridine (4,4'-bipy) can also form complexes with transition metal ions. Because of its structure, 4,4'-bipyridine can bridge between metal ions to form ‘coordination polymers’.
For example, nickel(II) can form a coordination polymer with 4,4'-bipyridine
containing {[Ni(H2O)4(4,4'-bipy)]2+}n chains.
Draw a 3-D diagram to predict the repeat unit in this coordination polymer of nickel(II).
Your diagram should show the complete structure of 4,4'-bipyridine and all coordinate bonds.

Have no idea how to do this chemistry question!!!

the first step would be to look up the structure of pyridine
then 4,4-bipyridine.

The nitrogen atoms of the heterocyclic ring coordinate to the central metal ion. The remaining ligand sites are taken up with water molecules.

Thanks so much for the answer I was so confused about it as well but do we need to know what coordinate polymers are for Alevel- ocr a specifically?
