A new cyclosilicate hydrate with composition (C 6 H 14 N) 4 Γ[Si 8 O 16 (OH) 4 ]Γ12H 2 O was crystallized and the structure determined by single-crystal X-ray diffraction. The structure, described by the tetragonal space group I4 1 /a, with unit cell dimensions of a = 39.2150(2) Γ and c = 14.1553(2)
Ab initio techniques inclusive of electron correlation (MP2) are used to study the gas-phase dimerization of water tetramers (T) into octamers (0), which is relevant to a model for the specific heat of liquid water. The T species has one basic structure, whereas three different conformations for the
