Question

Write formula of dichloro bis (ethylenediammine) platinum (iv) ion. ​

Answer 1

Answer:

The chemical formula for trans-dichloro bis(ethylenediamine)platinum(IV) is: trans-[Pt(en)2Cl2]2+ [ P t ( e n ) 2 C l 2 ] 2 + .

Answer 2

Final answer:

Chemical formula of dichlorobis(ethylenediammine)platinum(iv) ion is $[PtCl_{2}(en)_{2}]^{2+}$.

Given that: We are given dichlorobis(ethylenediammine)platinum(iv) ion.

To find: We have to find  formula of dichlorobis(ethylenediammine)platinum(iv) ion.

Explanation:

• The formula of a coordination complex is written by using following rules.

1). The chemical symbol of the central metal atom is written first.

2). Followed by ligands. Ligands are listed in alphabetical order. If more than one anion or neutral ligand s are there, they are written in alphabetical order according to the first letter in their chemical formula.

3). The formula is enclosed in square bracket. The formula of polyatomic ligands are enclosed in parenthesis. Abbreviations of ligands are also enclosed in parenthesis. Number of same ligand linked to central l atom is written in subscript after ligands are enclosed in parenthesis.

4). No space between metal and ligands within coordination sphere. Charge is indicated outside of the square bracket as a right superscript with the number before the sign.

Given that, dichlorobis(ethylenediammine)platinum(iv) ion.

• Here, central metal atom is platinum.

• Ligands: 2 $Cl^{-}$ ligand and 2 $en$ ligand. Ethylenediammine represented as "$en$".

• The given compound is a cation complex.

• By following above rules, the chemical formula of dichlorobis(ethylenediammine)platinum(iv) ion is $[PtCl_{2}(en)_{2}]^{2+}$.
