Abstract:
Two 1,2,4-diazaphospholide complexes of [Ti(η(2)-3,5-Ph(2)dp)(4)] and paramagnetic [Ti(η(2)-3,5-tBu(2)dp)(3)] were prepared by the reaction of tetrakis(dimethylamido)titanium(IV) with 3,5-diphenyl-1,2,4-diazaphophole, H[3,5-Ph(2)dp], or by the treatment of 3,5-tert-butyl-1,2,4-diazaphopholide potassium, K[3,5-tBu(2)dp], with titanium trichloride. Complexes can be viewed as the core of P(σ(2)λ(3))-functionalized metallodendrimers, in which the metal atoms are exclusively η(2)(N,N) bonding to the 1,2,4-diazaphospholides while P atoms (σ(2)λ(3)) with electron lone pairs are located on the periphery of the molecules.

02:46Crystal 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,...
