Abstract

A fully ordered structure is reported for the polymorph of triphenylsilanol-4,4 0 -bipyridyl (4/1), 4C 18 H 16 OSiÁC 10 H 8 N 2 , having Z 0 = 4. The asymmetric unit contains four similar but distinct five-molecule aggregates, in which the central bipyridyl unit is linked to two molecules of triphenylsilanol via O--H...N hydrogen bonds, with a further pair of triphenylsilanol molecules linked to the first pair via O-- H...O hydrogen bonds. An extensive series of C-- HÁ Á Á(arene) hydrogen bonds links these aggregates into complex sheets. This structure is compared with a previously reported structure [Bowes, Ferguson, Lough & Glidewell (2003). Acta Cryst. B59, 277-286], which was based on an erroneous disordered structural model arising from a false direct-methods solution with reference to a strong pseudo- inversion centre.
