The lattice structure of a pure and completely siliceous sample of zeolite ZSM-11 has been investigated by a combination of high-resolution solid-state {sup 29}Si MAS NMR and synchrotron-based X-ray powder diffraction techniques. The structure is temperature dependent in the range 263-363 K and a good fit to the diffraction data at 363 K is obtained with space group I{anti 4}m2 and a{sub 0} = 20.067 (1) and c{sub 0} = 13.411 (1). At room temperature the XRD data cannot be refined as the structure is intermediate and the lattice structure of the limiting low-temperature, low-symmetry form will only be deduced from data collected at 263 K.
