Shows 1-6 coordinate systems: terminal, linear, bent, trigonal, pyramidal, tetrahedral, trigonal-bipyramidal, octahedral. Lone pairs are represented by brown spheres or brown pear-shaped parts.
The Molymod molecular orbital system uses standard shiny colored atom parts to represent the central atom cores. Average scale is 3.5 cm per Angstrom. The atomic and molecular orbital parts are represented by pastel/matte colored pieces and are color-coded according to their use.
The pink and purple pear-shaped lobes and concave π links represent the +ve and -ve signs of the wave functions Ψ of the lobes of atomic and molecular orbitals. The gray pieces represent hybridized sigma bonds. The light brown spheres are used to indicate lone electron pair orbitals. Where the electrons are involved in hydrogen bonding, a light brown pear-shaped lobe is used
