What is the IUPAC name of this compound [Pt(Py)4][Pt(Cl4)]?
Answers
Explanation:
IUPAC Name is Tetrapyridineplatinum(II) Tetrachloridoplatinate(II)
Explaination :-
Here, [Pt(py)4] [Pt(Cl)4]
First complex is cationic complex. So, we write name of first complex with Cationic rule :-
Here,
ligan number = 4
ligan name = pyridine (py)
metal name (English) = platinum
So,
IUPAC name of Cationic complex is
Tetrapyridineplatium()
Give a bracket for entering O.N.
we write O.N. in last.
Now,
In Anionic complex :-
ligan number = 4
ligan name = chlorido (CL)
metal name (Latin + -ate) = platinate
So,
IUPAC name of Anionic complex is
Tetrachloridoplatinate()
Calculation of O.N. :-
Let the oxidation number of Pt in cationic complex be x
And
The oxidation number of Pt in anionic complex be y
Now,
→ x + 0×4 + y - 1× 4 = 0 [we know that sum of O.N. in all atoms of a molecule is zero]
→ x + y = 4
Now,
Divide 4 in two equal part
It means 2 and 2.
Now,
Put 2 as oxidation number of Pt in cationic complex.
In Cationic complex :-
Tetrapyridineplatinum(II)
In Anionic complex :-
Tetrachloridoplatinate(II)
Note :-
The oxidation number is written in Roman number.
Answer:
tetrapyridineplatinum(ll) tetrachloroplatinate (ll)
