WebDec 30, 2024 · Point-charge crystal field theory (CFT) for linear ML2systems guarantees dz2>dxz/dyz>dxy/dx2-y2 (i. e. dσ>dπ>dδ). This is not what is found for CuCl2and other linear, divalent MX2complexes where dπ>dσ. This failure of CFT has also been attributed to its successor, ligand field theory (LFT). WebThis electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals. CFT focuses on the nonbonding electrons on the central metal ion in coordination complexes not on the metal-ligand bonds.

WebThe crystal field theory (CFT) was developed for crystalline solids by the physicist Hans Bethe in 1929. The model takes into account the distance separating the positively and negatively charged ions and treats the ions simply as point charges with the attractive and repulsive interactions between them as purely electrostatic/ionic ones. http://chemiris.labs.brocku.ca/~chemweb/courses/chem232/CHEM2P32_Lecture_10.html the walking dead the althea tapes
