Yw. Li et al., HYDROGEN-BONDING IN FERROCENE DERIVATIVES - STRUCTURES OF 1-FERROCENYL-2,2-DIMETHYLPROPAN-1-OL AND 2,2'-(1,1'-FERROCENEDIYL)DI(PROPAN-2-OL), Acta crystallographica. Section C, Crystal structure communications, 50, 1994, pp. 857-861
In 1-ferrocenyl-2,2-dimethylpropan-1-ol, [Fe(C5H5){(C5H4)CH(OH)tBu}] (
I), the molecules are linked by hydrogen bonds to form ribbons around
crystallographic 2(1) axes; the O ... O distance in the hydrogen bonds
is 2.802 (11) angstrom and the molecules are disordered with R and S
enantiomers occupying common sites. The diol 2,2'-(1,1'-ferrocenediyl)
di(propan-2-ol), [Fe{(C5H4)CMe2OH}2] (II), crystallizes as centrosymme
tric dimeric aggregates containing fully ordered hydroxyl groups; the
dimers are formed by hydrogen bonding, with O ... O distances of 2.811
(2) and 2.841 (2) angstrom.
