Crystals of anhydrous chromium(I) chloride are violet and insoluble in aqueous solution. The coordination geometry of chromium in these crystals is octahedral as is almost always the case for Cr³+. How can this be the case if the ratio of Cr to Cl is not 1:6? Some of the Cr+ ions must be coordinated to other Cr+ ions. Some of the Cl ions must be coordinated to other Cl ions. Some or all of the Cl¯ ions must be shared by more than one Cr³+ ion. Some or all of the Cr*+ ions must be shared by more than one CI¯ ion.

When the copper (II) sulphate solution is reacted with a bidentate ligand such as ethylenediamine (en), the same thing would have happened. However, since one bidentate ligand has two donor atoms (Brown et al, 2017), each Cu2+ ion would only have 3 ligands at most, instead of 6 when reacted with monodentate ligands. The equation of the reaction is as follows: [Cu(H2O)6]2+(aq) + 3en(aq) → [Cu(en)3](aq) + 6H2O(ℓ) a. How do we know how many ligands can enter? b. Explain briefly the discussion above.

A compound formula with brackets is called a coordination complex, and the structure looks like a covalent compound with a transition metal central atom. The bonding that happens is often a hybrid of covalent and metallic bonding. One method of extracting silver from mined ore is by using a complex, K[Ag(CN)2], to make the silver soluble in water. The complex is then isolated to recover the silver using the following chemical equation. 2 K[Ag(CN)2] (aq) + Zn (s) → 2 Ag (s) + Zn(CN)2 (aq) + 2 KCN (aq) a.) 5.00 L of 1.25 M K[Ag(CN)2] is mixed with 215.5 g of zinc.
