1,1'-Bis(1-acetyl-5-methyl-1H-pyrazol-3-yl)ferrocene
Abstract:
The title compound, [Fe(C(11)H(11)N(2)O)(2)], crystallizes with two independent mol-ecules in the asymmetric unit which have have different conformations. In one mol-ecule, the two ferrocene cyclo-penta-dienyl rings are fully eclipsed and the two pyrazole rings are syn to each other; in the other, the two cyclo-penta-dienyl rings are synclinal and the pyrazole rings are anti. In both mol-ecules, the acetyl group attached to the pyrazole ring is oriented away from the iron-cyclo-penta-dienyl group of ferrocene.

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...
