✦ Synopsis
In the title compound, C 14 H 30 O 4 Si, the bond angles around Si are in the range 105.4 (3)-112.1 (4) and the tetrahydrofuran ring adopts a distorted envelope conformation. There is one intramolecular and one intermolecular O-HÁ Á ÁO hydrogen bond in the crystal structure. A spiral of molecules forms around the 4 1 axis (c axis) of the crystal structure via the intermolecular O-HÁ Á ÁO hydrogen bond.
