Step 1: Identify the central atom. In this case, the central atom is Ruthenium (Ru).
Step 2: Identify the ligands. The ligands are ethylenediamine (en) and Chlorine (Cl). Ethylenediamine is a bidentate ligand, meaning it can form two bonds with the central atom.
Step 3: Identify the geometry of the complex. Since there are 6 coordination sites (2 from each ethylenediamine and 1 from each chlorine), the geometry is octahedral.
Step 4: Sketch the structure. Place the Ruthenium atom at the center. Draw two ethylenediamine ligands and two chlorine atoms around the Ruthenium. Make sure to place the two chlorine atoms next to each other (cis configuration).
Step 5: Name the compound. The full name of the compound is cis-dichlorobis(ethylenediamine)ruthenium(II). The 'cis' indicates that the two chlorine atoms are next to each other. The 'dichloro' and 'bis(ethylenediamine)' indicate the ligands present and their quantities. The 'ruthenium(II)' indicates the central atom and its oxidation state.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Coordination Compounds

Coordination compounds consist of a central metal atom bonded to surrounding molecules or ions called ligands. The arrangement and type of ligands influence the properties and reactivity of the complex. Understanding the nature of these interactions is crucial for sketching the structure of coordination complexes.

Coordination Compound Naming

Stereochemistry

Stereochemistry involves the study of the spatial arrangement of atoms in molecules. In coordination chemistry, the geometry of the complex, such as cis or trans configurations, affects its physical and chemical properties. Recognizing these arrangements is essential for accurately depicting the structure of the given compound.

Nomenclature of Coordination Compounds

The nomenclature of coordination compounds follows specific rules set by the International Union of Pure and Applied Chemistry (IUPAC). This includes naming the ligands, indicating their number, and specifying the oxidation state of the metal. Properly naming the compound is vital for clear communication in chemistry.
