Chapter 21, Problem 82b
Write the formula for each of the following compounds.
(c) Tris(ethylenediamine)platinum(IV) sulfate
(d) Triamminetrithiocyanatorhodium(III)
Verified step by step guidance1
Understand the naming conventions for coordination compounds.
For (c) Tris(ethylenediamine)platinum(IV) sulfate: Identify the central metal, ligands, and oxidation state.
For (c): Platinum is the central metal with an oxidation state of +4, ethylenediamine is a neutral bidentate ligand, and sulfate is the counter ion.
For (d) Triamminetrithiocyanatorhodium(III): Identify the central metal, ligands, and oxidation state.
For (d): Rhodium is the central metal with an oxidation state of +3, ammonia is a neutral ligand, and thiocyanate is a monodentate ligand.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Coordination Compounds
Coordination compounds consist of a central metal atom bonded to surrounding molecules or ions called ligands. The ligands can be neutral or charged and can vary in number and type. Understanding how to identify the central metal and the ligands is crucial for writing the correct chemical formula.

Coordination Compound Naming
Oxidation States
The oxidation state of a metal in a coordination compound indicates its charge and is essential for determining the overall charge of the compound. In the given examples, recognizing the oxidation states of platinum and rhodium helps in correctly balancing the charges with the ligands and any counterions present in the formula.

02:42Oxidation Numbers
Nomenclature of Coordination Compounds
The nomenclature of coordination compounds follows specific rules set by IUPAC, which dictate how to name the ligands, the central metal, and the overall compound. This includes the order of ligands, the use of prefixes to indicate the number of each type of ligand, and the appropriate suffixes for the metal based on its oxidation state.
