摘要

The title compound, [Fe(C5H5)(C11H13N2O)]center dot[Fe(C5H5)(C11H13N2O)]Cl, cocrystallizes as (1-2-hydroxyethyl-5methylpyrazol-3- yl)ferrocenium chloride-(1-2-hydroxyethyl-5-methylpyrazol-3-yl)ferrocene(1/1). Two independent pyrazolylferrocenes in the asymmetric unit, with similar geometric parameters, form an R-4(4)(24) tetramer via O-H center dot center dot center dot N hydrogen bonds and Cl- ions occupy the spaces between the tetramer rings. This tetramer is linked via C - H center dot center dot center dot pi hydrogen bonds, involving the cyclopentadienyl rings as acceptors, into a [100] chain.
