(d) [Cr(NH3)2(C2O4)2]-

검증된 단계별 안내
1
Identify the central metal ion in each complex and determine its oxidation state.
For complex (c), [Fe(H_2O)_5NCS]^2+, identify the ligands: water (H_2O) and thiocyanate (NCS). Water is a neutral ligand, and thiocyanate is a monodentate ligand with a charge of -1.
Determine the oxidation state of iron (Fe) in complex (c) by considering the overall charge of the complex (+2) and the charges of the ligands.
For complex (d), [Cr(NH_3)_2(C_2O_4)_2]^-, identify the ligands: ammonia (NH_3) and oxalate (C_2O_4). Ammonia is a neutral ligand, and oxalate is a bidentate ligand with a charge of -2.
Determine the oxidation state of chromium (Cr) in complex (d) by considering the overall charge of the complex (-1) and the charges of the ligands.

주요 개념

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

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, whether they are neutral or charged, and their arrangement around the metal center significantly influence the compound's properties and nomenclature.

Coordination Compound Naming

Ligand Naming and Classification

Ligands are classified based on the number of donor atoms they possess. Monodentate ligands bind through a single atom, while bidentate and polydentate ligands can attach through multiple atoms. The systematic naming of ligands follows specific rules, such as using prefixes like 'di-', 'tri-', and 'tetra-' to indicate the number of identical ligands present.

Ligand Classification

Oxidation States and Charge

The oxidation state of a metal in a coordination compound is crucial for determining its systematic name. It reflects the charge of the metal ion after accounting for the charges contributed by the ligands. Understanding how to calculate the overall charge of the complex is essential for correctly naming the compound and ensuring that the name reflects its chemical identity.
