Abstract:
The title complex, systematic name hexa-kis-(μ2-4-tert-but-oxy-4-oxobut-2-en-2-olato)-1:2κ(9) O (2),O (4):O (2);2:3κ(9) O (2),O (4):O (2)-trizinc, [Zn3(C8H13O3)6], syn-the-sized from tert-butyl aceto-acetate and di-ethyl-zinc, consists of trinuclear centrosymmetric mol-ecules of an approximate C 3i symmetry. The three metal cations are arranged in a linear fashion, with the central Zn(II) atom located on a centre of symmetry. All three metal cations exhibit a distorted octa-hedral coordination geometry. The terminal Zn(II) cations are chelated by three tert-butyl aceto-acetate ligands and these units are connected to the central Zn(II) atom by the bridging enolate O atoms.

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...

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...
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.
CFT focuses on...
