Abstract

The title compound, [Fe(C11H11N2O)2], crystallizes with two independent mol­ecules in the asymmetric unit which have have different conformations. In one mol­ecule, the two ferrocene cyclo­penta­dienyl rings are fully eclipsed and the two pyrazole rings are syn to each other; in the other, the two cyclo­penta­dienyl rings are synclinal and the pyrazole rings are anti. In both mol­ecules, the acetyl group attached to the pyrazole ring is oriented away from the iron–cyclo­penta­dienyl group of ferrocene.
