Trigonal prism Geometry: Most trigonal prismatic compounds have three bidentate ligands such as dithiolates or oxalates and few are known for first row transition metal ions. In contrast, quantum-chemical gas-phase calculations show the square-antiprismatic coordination polyhedron (point group S 8 ) to be energetically favored over the bicapped trigonal prism and the latter is not even a true local minimum. Yamana, Shukichi. Yamana, … In contrast, quantum‐chemical gas‐phase calculations show the square‐antiprismatic coordination polyhedron (point group S 8 ) to be energetically favored over the bicapped trigonal prism and the latter is not even a true local minimum.
