【 摘 要 】

The asymmetric unit of the title compound {systematic name: 3-[(tert-butyl­diphenyl­sil­yl)­oxy]propane-1,2-diol, C19H26O3Si}, contains eight chiral mol­ecules (Z′ = 8). These mol­ecules are connected via a complex system of hydrogen bonds into an infinite assembly along the [100] axis; hydro­phobic tert-butyl and phenyl groups form an external coating of the assembly. These assemblies are packed by weak inter­molecular inter­actions in a peculiar formation resembling a `header bond' masonry brick wall. Disorder of flexible fragments increases with temperature but the same crystal structure exists from 120 to 220 K (and most probably to the melting point at 334 K).
