4. ORGANOPLATINUM
ORGANOPLATINUM CHEMISTRY IS
A CHEMISTRY OF
ORGANOMETALLIC COMPOUNDS
CONTAINING A CARBON TO
PLATINUM BOND AND THE STUDY
OF PLATINUM AS A CATALYST

5. -
ORGANOPLATINUM COMPONDS
EXIST IN THE OXIDATION STATE 0
TO IV ,WITH OXIDATION STATE (II)
MOST ABUNDANT

6. ORGANOPLATINUM (0)
 MOST ORGANOPLATINUM (0)
COMPOUNDS CONTAIN ALKENE AND
ALKYNE LIGANDS.
 THE ALKENE AND ALKYNE LIGANDS
SERVE AS TWO ELECTRON
DONORS.
 Eg: (PPh₃)₂Pt(C₂H₄) AND
(PPh₃)₂Pt(C₂Ph₂) .
 NITROGEN BASED LIGANDS DO NOT OFTEN
SUPPORT THE FORMATION OF PLATINUM
COMPLEXES OF ALKENES AND ALKYNES .

7. ORGANOPLATINUM (1)
 PLATINUM (I) COMPOUNDS ARE
UNCOMMON BUT GENERALLY
ARE DIMAGNETIC BECAUSE THEY
HAVE Pt-Pt BONDS.
 Eg : [Pt₂(CO)₆]

8. ORGANOPLATINUM (II)
 A HISTORICALLY SIGNIFICANT
ORGANOPLATINUM(II) COMPOUND
IS ZEISE’S SALT ,WHICH IS OBTAINED
FROM ETHYLENE AND POTASSIUM
TETRACHLOROPLATINATE.
 PLATINUM ALLYL COMPLEXES ARE ALSO
COMMON .

9. ORGANOPLATINUM (IV)
 THE FIRST ORGANOPLATINUM
COMPOUND EVER SYNTHESISED
WAS TRIMETHYL PLATINUM
IODIDE FROM PLATINUM (IV)
CHLORIDE AND METHYL
MAGNESIUM IODIDE
 THE COMPOUND ADOPTS A
CUBANE LIKE STRUCTURE WITH
FOUR TRIPLY BRIDGING IODIDE
LIGANDS .
