Question

IUPAC name of the chemical compound \( \text{Ni(PPh}_3)_2\text{Cl_2 \) \( 2+ \)?}

Hint:

When naming coordination compounds, remember to list the ligands alphabetically, and use prefixes like "bis", "tris", etc., to indicate multiple identical ligands.

Answer 1

The IUPAC name of the given compound \( \text{Ni(PPh}_3)_2\text{Cl}_2 \) \( 2+ \) is "Bis(triphenylphosphine) dichloronickel(II)". In this compound: - The nickel (Ni) is in the +2 oxidation state, - There are two triphenylphosphine (PPh3) ligands and two chloride (Cl) ligands attached to the nickel center. In the IUPAC name: - "Bis" indicates two identical ligands (triphenylphosphine), - "Dichloro" refers to the two chloride ions, - "Nickel(II)" indicates the metal center with a +2 oxidation state.
