Crystal structure of a second polymorph of 2-cyclo-penta-dienyl-1,7-dicarba-2-cobalta-closo-dodeca-borane(11).
A new polymorph of the title compound 2-(η-C5H5)-2,1,7-closo-CoC2B9H11, [Co(C5H5)(C2H11B9)], in the space group P21/n has been characterized, including the unambiguous location of both cage C atoms. The precision of this study is an order of magnitude greater than that of the first polymorph [C2/c; Lopez et al. (2010). Collect. Czech. Chem. Commun. 75, 853-869].
