Coordination Chemistry Simulator

Interactive transition-metal complex builder: switch between octahedral, tetrahedral, square-planar and linear coordination geometries and watch the real 3D ligand arrangement update. A live crystal field theory panel shows the d-orbital energy-level diagram splitting, lets you tune ligand field strength along the spectrochemical series and d-electron count, and derives high-spin/low-spin configuration and complex colour from the resulting splitting Delta.
