Abstract:
The structures of five hydrogen-bonded adducts of triphenylsilanol, Ph 3 SiOH, with diamines have been determined. In the 4:1 adduct formed with 1,4-diazabicyclo[2.2.2]octane, (Ph 3 SiOH) 4 ·C 6 H 12 N 2 (I) (triclinic, P \bar 1, Z ′ = 2), there are two independent five-component aggregates built from O—H...N and O—H...O hydrogen bonds, in one of which the diamine exhibits orientational disorder: these two aggregates are linked into a cyclic ten-molecule unit by means of two independent C—H...π(arene) hydrogen bonds. The 4:1 adduct formed with 1,2-bis(4-pyridyl)ethene, (Ph 3 SiOH) 4 ·C 12 H 10 N 2 (II) (triclinic, P \bar 1, Z ′ = 0.5), forms a similar five-component aggregate which lies across a centre of inversion: a single C—H...π(arene) hydrogen bond links these aggregates into a molecular ladder. With N , N ′-dimethylpiperazine, triphenylsilanol forms a 2:1 adduct, (Ph 3 SiOH) 2 ·C 6 H 14 N 2 (III) (monoclinic, P 2 1 / c , Z ′ = 0.5), in which a three-component aggregate built from O—H...N hydrogen bonds lies across a centre of inversion: two independent C—H...π(arene) hydrogen bonds link these aggregates into sheets. In the hydrated 2:1 adduct formed with 1,2-bis(4′-bipyridyl)ethane, (Ph 3 SiOH) 2 ·C 12 H 12 N 2 ·H 2 O (IV) (triclinic, P \bar 1, Z ′ = 1), a combination of two independent O—H...O and two independent N—H...O hydrogen bonds links the five molecular components into a centrosymmetric eight-molecule aggregate, and six independent C—H...π(arene) hydrogen bonds link these chains into a continuous three-dimensional framework structure. In the dihydrated 2:1 adduct formed with 4,4′-bipyridyl, (Ph 3 SiOH) 2 ·C 10 H 8 N 2 ·(H 2 O) 2 (V) (triclinic, P \bar 1, Z ′ = 1), a combination of four independent O—H...O and two independent N—H...O hydrogen bonds links the five molecular components into a chain of rings, and four independent C—H...π(arene) hydrogen bonds link these chains into a continuous three-dimensional framework structure.
