Abstract:
An X-ray investigation of the two uranyl 8-hydroxy-quinolates UO(2).(C(9)H(6)NO)(2).C(9)H(6)NOH (dark red) and [UO(2).(C(9)H(6)NO)(2)](2).C(9)H(6)NOH (orange), has been carried out on the untreated compounds and after recrystallising them from chloroform. The unsolvated compound UO(2).(C(2)H(6)NO)(2) and the residue remaining after dissolving the orange compound in chloroform have also been examined. The investigation shows that the crystals obtained from the red and orange compounds, respectively, after dissolving in chloroform and recrystallising, are identical. The untreated red and orange compounds are different, the latter showing evidence of existing as a polymer, whereas the former is crystalline. On the basis of the results obtained, a structure for the orange compound is proposed.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

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,...

02:58Crystal 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.
