An ortho-rhom-bic polymorph of 1-[(ferrocen-yl)(hydr-oxy)meth-yl]-1,2-dicarba-closo-dodecaborane.


ABSTRACT: An ortho-rhom-bic polymorph of the title compound, [Fe(C(5)H(5))(C(8)H(17)B(10)O)] or C(13)H(22)B(10)FeO, is described here in addition to the known monoclinic polymorph [Crundwell et al. (1999 ?). Acta Cryst.C55, IUC9900087]. The asymmetric unit contains four independent mol-ecules with C(cage)-C(cage) distances of 1.636?(16)-1.700?(16)?Å, and with the methyl-hydr-oxy groups disordered over two positions in each mol-ecule [occupancy ratios 0.80?(2):0.20?(2), 0.59?(3):0.41?(3), 0.60?(2):0.40?(2) and 0.793?(17):0.207?(17)].
