Abstract
In the isomorphous 2:1 adducts of furan-2,5-diylbis-(diphenylmethanol) with dimethylformamide, (DMF), [2(C 30 H 24 O 3 ):1(C 3 H 7 NO)] (II), and with dimethyl sulfoxide (DMSO), [2(C 30 H 24 O 3 ):1(C 2 H 6 OS)] (III), the centrosymmetric molecular aggregate consists of two molecules of the diol, linked via O-H...O hydrogen bonds involving only the hydroxyl O atoms, and one molecule of either DMF or DMSO disordered across other centres of inversion and linked to the diol dimer by OPH...O hydrogen bonds. In the 2:1 adduct with pyridine, [2(C 30 H 24 O 3 ):1(C 5 H 5 N)] (IV), the molecular aggregate is similar in structure to those in (II) and (III), but with detailed differences in the hydrogen-bonding scheme within the diol dimer.
