Abstract:
Two isostructural eight-coordinate complexes Ln(NO3)3(tBu3PO)2 (Ln = Yb, 1-Yb; Tb, 2-Tb) were synthesized and structurally analyzed by single-crystal X-ray crystallography. Both complexes feature a nearly perfect hexagonal bipyramidal LnO8 geometry with ideal D3h symmetry. Magnetic measurements show field-induced slow magnetic relaxation for 1-Yb, thereby presenting the first report of YbIII-based SIMs with a hexagonal bipyramidal coordinate geometry. In contrast, 2-Tb shows no significant out-of-phase (χ''M) ac signals.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This 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.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal 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. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
