Name the following: [Ni(NH₃)₃(H₂O)₃]Cl₂ A) nickel(II) trihydrotriamminechloride B) nickel(I) triamminetrihydrochloride C) dichloronickel(II) triamminetrihydride D) nickel(III) chloride E) triamminetriaquanickel(II) chloride

Question

Quizplus · Accepted Answer

The ligands in the square brackets indicate that this is a coordination compound containing nickel as the central metal ion. The ligands are:
- four ammine ligands (NH3), each with one nitrogen to coordinate to the metal ion
- two thiolate ligands (HS-), each with one sulfur atom to coordinate to the metal ion
- one aqua ligand (H2O), with two oxygen atoms to coordinate to the metal ion
The overall charge of the complex is zero, which indicates a nickel(II) complex. The chloride ion (Cl-) in the outer sphere is balanced by the aqua ligand. The correct name for this compound is triamminetriaquanickel(II) chloride.
