WebNational Council of Educational Research and Training WebCrystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. WebOct 4, 2024 · Ligand Field Theory looks at the effect of donor atoms on the energy of d orbitals in the metal complex. There are two ways in which we sometimes think about the effect of ligands on the d electrons on a metal. On the basis of simple electron-electron repulsion, donation of a lone pair might raise an occupied d orbital in energy. diapers for 12 year old boy
