title: Hydrogen-bonded adducts of ferrocene-1,1'-diylbis(diphenylmethanol): monomeric and dimeric 1:1 adducts with 1,2-bis(4-pyridyl)ethane and 1,2-diaminoethane.
abstract: In ferrocene-1,1'-diylbis(diphenylmethanol)-4,4'-ethylenedipyridine (1/1), [Fe(C(18)H(15)O)(2)].C(12)H(12)N(2), there is an intramolecular O-H...O hydrogen bond in the ferrocenediol component and a single O-H...N hydrogen bond linking the two components into a finite monomeric adduct. Ferrocene-1,1'-diylbis(diphenylmethanol)-ethylenediamine (1/1), [Fe(C(18)H(15)O)(2)].C(2)H(8)N(2), crystallizes with Z' = 2 in space group P1, and there are two independent four-component aggregates in the structure, both of which are centrosymmetric. In the first type of aggregate, the molecular components are linked by O-H...N and N-H...O hydrogen bonds, in which both diamine N atoms participate; in the second type of aggregate, the diamine component is disordered over two sets of sites, but only one N atom is involved in the hydrogen bonding.
