A coordination compound of ruthenium, [Ru(NH 3 ) 4 Cl 2 ]Cl, has shown some activity against leukemia in animal studies. The [Co(NH3)4Cl2] complex must have a net charge of +1 (since it pairs up with one Cl- ion) and as you correctly stated, the NH3 ligand has no charge; the only charged species in the complex ion are the cobalt ion and the two chloride ions: Co(?) The first three complexes can have cis and trans isomers. : A • The common name of this compound is potassium ferrocyanide. 8 • Chlorophyll, involved in photosynthesis, is a complex ion of magnesium(II) ion. 7 Coordination Complexes. Suppliers Rules for Nomenclature 1. Rule 2: The name of the coordination compound (neutral, cationic or anionic) begins with the names of the ligands. Cl is -1 therefore the overall charge of the complex is +1, ie the formula is [Co(NH3)4Cl2]+. Chemical Product The complex ion is an anion, therefore the name will end in ferrate(III) Ligands are named before central metal ion: hexacyanidoferrate(III) Examples of Names of Complex Ions . Chlorine atoms almost always -1, therefore the counter ions (Cl2) give a net charge of -2. L T The coordinate complex is always enclosed in square brackets, [ ]. A coordination compound of ruthenium, [Ru(NH. F The last compound however can only be Cis as there are too many Cl for a trans isomer to be formed. G Reaction of [Co(CO 3)(NH 3) 4] + with concentrated HCl produces the cis isomer. What is the molecular formula and the chemical name of the molecule shown in the picture? However reaction of [Co(NH 3) 6] 3+ with a mixture of HCl and H 2 SO 4 gives the trans isomer. Properties Structure Search. in this complex, and Cl is the ligand and this is the example of octahedral complex type. Coordination compounds, such as the FeCl 4-ion and CrCl 3 6 NH 3, are called such because they contain ions or molecules linked, or coordinated, to a transition metal.They are also known as complex ions or coordination complexes because they are Lewis acid-base complexes. there would be geometrical isomers -> cis isomer and trans isomer there would be no optical isomer due to plane of symmetry in the coordination compound mer-[Ru(PPh 3) 3Cl 3] mer-trichlorotris(triphenylphosphine)ruthenium(III) Here the coordination complex is neutral, so no spaces are necessary. Coordination compounds (or complexes) are molecules and extended solids that contain bonds between a transition metal ion and one or more ligands. The coordinate complex itself consists of a transition metal atom or ion and the surrounding ligands. Our videos will help you understand concepts, solve your homework, and do great on your exams.

Gram formula weight (molecular mass) = 167.69 Tetraamminodiaquachromium(III) ion (four ammonia and two water ligands) is octahedral and is coloured deep blue-violet. Nomenclature of Coordination Compounds • Nomenclature follows different rules than for normal inorganic compounds • Name the cation and the anion separately • Follow the same rules for coordination compounds and complex ions. The complex ion is associated with counter ions of opposite charge. 23-11 12. S • Since there are 4 K+ associated with the complex ion (each K + having a +1 charge), the charge on the complex ion must be -4. • Since each ligand carries –1 charge, the oxidation number of Fe must be +2. Orbitals of Co3+ ion: Again, fluoride ion is a weak field ligand. Counter ions are needed to produce a neutral coordinate compound if the complex is an ion.
