Abstract:
The aim of the current study was to examine the effects of group 13 metals on Cp2TiCl2 reduction in the presence of 2-methoxyethanol (MeOEtOH) or ethanol (EtOH) and the compositions of the resulting products. Direct reaction of Cp2TiCl2 and M [Al, Al (Fe contaminated), Ga, In] in toluene/alcohol for 2 h gave a new family of uncommon homo- and heterometallic compounds: [Cp2Ti2Al(μ,η2-OEtOMe)4Cl2][Ti2(μ,η2-OEtOMe)3(η2-OEtOMe)2Cl4] (1), [Cp2Ti2Al(μ,η2-OEtOMe)4Cl2]Cl (2), [Cp2Ti2Al(μ,η2-OEtOMe)4Cl2][Cp2Ti(η2-HOEtOMe)][FeCl4] (3), [Cp2Ti(η2-HOEtOMe)][Ga2Cl6]0.25[Cl]0.5 (4), [Cp3Ti2(μ-OEt)2(OEt)][GaCl4] (5), [CpTi(μ,η2-OEtOMe)Cl]2 (6), and [Cp3Ti2(μ,η2-OEtOMe)(μ-OEtOMe)Cl] (7). The reaction with indium for 48 h resulted in isolation of [TiIn2(μ,η2-OEtOMe)4(OEtOMe)2Cl4] (8), [In2(μ-OEtOMe)2(HOEtOMe)4Cl4]2 (9), and [Ti(OEtOMe)4] (10). The complexes were characterized using elemental analysis, IR and NMR spectroscopies, and, for 1-9, single-crystal X-ray diffraction. The use of metallic gallium and indium to reduce Cp2TiCl2 opens up a previously unexplored path that may provide access to novel and unique compounds.

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,...
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.
CFT focuses on...
