What is the systematic name for each of the following coordination compounds? 
(c) [Co(NH3)₄Br₂]Br
(d) Cu(gly)₂

Verified step by step guidance

1. Identify the central metal ion in each coordination compound. For (c), the central metal is cobalt (Co), and for (d), it is copper (Cu).
2. Determine the oxidation state of the central metal ion. For (c), consider the charge of the ligands and the overall charge of the complex. For (d), use the fact that glycine (gly) is a neutral ligand.
3. Name the ligands in alphabetical order. For (c), the ligands are ammine (NH_3) and bromo (Br). For (d), the ligand is glycinato (gly).
4. Combine the names of the ligands with the metal, including its oxidation state in Roman numerals. For (c), use the format: ligand names + metal name + oxidation state. For (d), use the format: ligand name + metal name + oxidation state.
5. For (c), since the complex ion is a cation, the name of the complex is followed by the name of the counterion (bromide). For (d), since there is no counterion, the name of the complex is complete.

Key Concepts

Coordination Compounds

Coordination compounds consist of a central metal atom or ion bonded to surrounding molecules or ions, known as ligands. The nature of these ligands and their arrangement around the metal center significantly influence the properties and reactivity of the compound. Understanding the structure and bonding in coordination complexes is essential for naming them systematically.

Ligands and Their Naming

Ligands are ions or molecules that donate electron pairs to the central metal atom in a coordination compound. They can be classified as monodentate (binding through one atom) or polydentate (binding through multiple atoms). The naming of ligands follows specific conventions, such as using prefixes to indicate the number of ligands and specific names for common ligands like ammonia (NH3) and bromide (Br-).

Systematic Naming of Coordination Compounds

The systematic naming of coordination compounds follows the IUPAC nomenclature rules, which dictate the order of naming the ligands, the metal, and its oxidation state. Ligands are named first in alphabetical order, followed by the metal name, which may include a Roman numeral to indicate its oxidation state. This systematic approach ensures clarity and consistency in the identification of coordination compounds.
