Two-dimensional molecular motions of guanidinium ions confined in the interlayer space of tetrasilicicfluormica
Dynamic behavior of guanidinium ions with the planar structure in the two-dimensional interlayer space of tetrasilicic-fluormica was investigated by the solid NMR method. Above 300 K, guanidinium ions were found to perform the two-dimensional self-diffusion with their molecular plane parallel to the clay layers.
