Can describe the system through which the complexes can be named according to the number of rules that were agreed upon by the International Union (IUPAC) for theoretical and applied chemistry 3D-Najlaa alradadi

1- When you write a compound formula must be written ion compound in square brackets [] Where the metal first written code And then order the coordinate groups as follows : negative, neutral and cationic groups. for example: [CoSO 4 (NH 3 ) 4 ]NO 3 [CoClCNNO 2 (NH 3 ) 3 ] 4D-Najlaa alradadi

2- To name the complex write the name of the positive ion first and then the negative ion as it is in simple salts. D-Najlaa alradadi5

5- Greek prefixes are used to designate the number of each type of ligand in the complex ion, e.g. di-, tri- and tetra-. If the ligand already contains a Greek prefix (e.g. ethylenediamine) or if it is polydentate ligands (ie. can attach at more than one binding site) the prefixes bis-, tris-, tetrakis-, pentakis-, are used instead The numerical prefixes are listed in Table 14D-Najlaa alradadi

D-Najlaa alradadi18 6- names of the elements that make up the central atom: For the anionic complexes, the name of the item ends with (ate), while in neutral or cationic complexes remains unchanged name of the item as it is without the addition of :

After naming the ligands, name the central metal. -If the complex ion is a cation, the metal is named same as the element. For example, Co in a complex cation is call cobalt and Pt is called platinum. -If the complex ion is an anion, the name of the metal ends with the suffix ate. For example, Co in a complex anion is called cobaltate and Pt is called platinate. For some metals, the Latin names are used in the complex anions e.g. Fe is called ferrate (not ironate). 19D-Najlaa alradadi

20 For historic reasons, some coordination compounds are called by their common names. For example, Fe(CN) 6 3- and Fe(CN) 6 4- are named ferriccyanide and ferrocyanide respectively, and Fe(CO) 5 is called iron carbonyl. For historic reasons, some coordination compounds are called by their common names. For example, Fe(CN) 6 3- and Fe(CN) 6 4- are named ferriccyanide and ferrocyanide respectively, and Fe(CO) 5 is called iron carbonyl.
