inorganic-chemistry

## What I do - Study elements and inorganic compounds - Analyze coordination chemistry and metal complexes - Investigate organometallic compounds - Research solid-state chemistry - Characterize inorganic reactions and mechanisms - Develop inorganic materials ## When to use me - When studying transition metal chemistry - When analyzing coordination compounds - When investigating organometallic reactions - When working with solid-state materials - When characterizing inorganic complexes - When developing catalysts ## Key Concepts ### Periodic Trends - Atomic radius: Decreases across period, increases down group - Ionization energy: Increases across period - Electronegativity: Increases across period - Electron affinity: Varies across period - Oxidation states: Variable for transition metals ### Coordination Chemistry **Ligand Types** - Monodentate: Single donor atom (NH₃, H₂O, Cl⁻) - Bidentate: Two donor atoms (en, oxalate) - Polydentate: Multiple donor atoms (EDTA) - Ambidentate: Multiple binding modes (SCN⁻, NO₂⁻) ```python # Example: Crystal field stabilization energy def cfse(electron_config, geometry): """ Calculate crystal field stabilization energy. electron_config: d-electron count geometry: 'octahedral' or 'tetrahedral' """ if geometry == 'octahedral': # For 6-coordinate: t2g ↑↓↑↓↑↓ > eg ↑↑ return {'d0': 0, 'd1': -4, 'd2': -8, 'd3': -12, 'd4': -6, 'd5': 0, 'd6': -4, 'd7': -8, 'd8': -12, 'd9': -6, 'd10': 0} elif geometry == 'tetrahedral': # For 4-coordinate: e ↑↓ > t2 ↑↑ return {'d0': 0, 'd1': -6, 'd2': -12, 'd3': -8, 'd4': -4, 'd5': 0, 'd6': -6, 'd7': -12, 'd8': -8, 'd9': -4, 'd10': 0} ``` ### Molecular Orbital Theory - Bonding and antibonding orbitals - d-orbital splitting in complexes - Spectrochemical series - Magnetic properties ### Important Compound Classes - Oxides, halides, sulfides - Coordination complexes - Organometallics - Cluster compounds - Solid-state materials
