. H 2 O. M r =1017.88, triclinic, space group P 1. The molecules are arranged in bilayers. The molecules in each bilayer are held together by electrostatic forces, i.e., O-N + contacts, and hydrogen bonds. The asymmetric unit consists of two partly disordered siloxane molecules and one water molecule. The structure of the bilayers is virtually the same at 163 K and room temperature, but the stacking of the bilayers is different. The Si-O-Si bond angles at low temperature are significiantly smaller than at room temperature.
