Abstract:
Magnetization as a function of applied pressure up to 10.16 kbar and magnetic field were obtained for layered [Ru(2)(O(2)CBu(t))(4)](3)[M(CN)(6)]·2H(2)O (M = Cr, Fe). For M = Fe, the T(c) increased by 13% from 6.1 to 6.9 K with a significant increase in the coercive field, H(cr), from 5 to 65 Oe, followed by a sharp decrease to less than 10 Oe at further applied pressure. A 32% increase in T(c) from 37.8 to 50.0 K was observed for M = Cr as well as a linear decrease of H(cr) upon increasing pressure from 6380 to 2380 Oe.

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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
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,...
