The crystal structure of the low temperature phase of poly(di-n-hexyl silane) (PdnHS) was determined by X-ray diffraction techniques. The backbone chain conformation was found to be all-trans and the unit cell to be orthorhombic with dimensions a = 1.376, b = 2.386 and c = 0.399 nm. There are two molecules in a unit cell belonging to the Pna21 space group. Intermolecular interactions between side chains appear to be predominantly responsible for the all-trans backbone. Intramolecular crystallization between the side chains of a molecule does not seem feasible.
