INTRODUCTION
A coordination compound is any of a class of substances with chemical structures in which a central metal atom is surrounded by nonmetallic atoms or groups of atoms, called ligands, joined to it by chemical bonds. The metal atom in a coordination compound may be an electrically neutral atom or an ion. The ligands may also be neutral or charged. A ligand forms a chemical bond with the metal atom by sharing a pair of electrons with it. A ligand can attach to the atom by one bond (unidentate) or several bonds (multidentate). The oxalates of the alkali metals and of ferrous iron are soluble in water; all other oxalates are either insoluble or sparingly soluble in water. They are all rather soluble in dilute acids. The compound to be prepared is potassium tris(oxalato)ferrate(III) trihydrate. It is an octahedral transition metal complex in which three bidentate oxalate ions are bound to an iron centre. The general equation of the reaction is;
