metal-organic compounds
In the 3:2 adduct formed between ferrocene-1,1′-diylbis[bis(4-methoxyphenyl)methanol] and methanol, 3[Fe(C20H19O3)2].2CH4O, the ferrocenediol occupies two types of site. Ferrocenediol molecules in general positions form intramolecular O-H
O hydrogen bonds and are hydrogen-bonded to methanol molecules by a single O-HO hydrogen bond, while ferrocenediol molecules lying across centres of inversion form no O-HO hydrogen bonds. Overall, only half of the hydroxyl groups in the asymmetric unit act as donors in O-HO hydrogen bonds, while none of the seven independent methoxyl groups acts as acceptors of O-HO hydrogen bonds.
