1,1'-Bis(1-acetyl-5-methyl-1H-pyrazol-3-yl)ferrocene.

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.
