Question:
The correct formula of dichlorobis(triphenylphosphine) nickel(II) is
The correct formula of dichlorobis(triphenylphosphine) nickel(II) is
Show Hint
In coordination compounds, \(PPh_3\) is neutral and \(Cl^-\) has charge \(-1\).
Updated On: Apr 29, 2026
- \([NiCl_2(PPh_3)_2]Cl\)
- \([NiCl_2(PPh_3)]\)
- \([NiCl_2(PPh_2)_3]\)
- \([NiCl(PPh_3)_2]Cl\)
- \([NiCl_2(PPh_3)_2]\)

The Correct Option is
Solution and Explanation
Concept:
The name dichlorobis(triphenylphosphine) nickel(II) means two chloride ligands and two triphenylphosphine ligands attached to \(Ni^{2+}\).
Step 1: Decode the name.
Dichloro means: \[ 2Cl^- \] Bis(triphenylphosphine) means: \[ 2PPh_3 \]
Step 2: Write metal oxidation state.
Nickel(II) means: \[ Ni^{2+} \]
Step 3: Form neutral complex.
Two chloride ions balance \(Ni^{2+}\), while \(PPh_3\) is neutral: \[ [NiCl_2(PPh_3)_2] \]
