Hydrogen-bonded adducts of ferrocene-1,1'-diylbis(diphenylmethanol): monomeric and polymeric adducts with 1,2-bis(4-pyridyl)ethene and 1,6-diaminohexane.

In the adduct ferrocene-1,1'-diylbis(diphenylmethanol)-1,2-bis(4-pyridyl)ethene (1/1), [Fe(C18H15O)2]*C12H10N2, there is an intramolecular O-H...O hydrogen bond in the ferrocenediol component and a single O-H...N hydrogen bond linking the diol to the diamine, which is disordered over two sets of sites, so forming a finite monomeric adduct. In the adduct ferrocene-1,1'-diylbis(diphenylmethanol)-1,6-diaminohexane (2/1), 2[Fe(C18H15O)2]*C6H16N2, the amine lies across a centre of inversion in space group P-1. There is an intramolecular O-H...O hydrogen bond in the ferrocenediol, and the molecular components are linked by O-H.N and N-H.O hydrogen bonds, one of each type, into a C3(3)(13)[R6(6)(12)] chain of rings.
