The objectives are to study the interaction of water molecules held in a channel in an organic matrix. We have structurally characterised a water tetramethylpiperididine complex in which the water molecules allign as essentially micro tubes of water throughout the crystal lattice. We are interested in the detailed structure of this water matrix especially the hydrogen bonding throughout the structure. The reason for the interest is by analogy to nature where water channels are common place. The planned research is to continue to modify the piperidene to allow the formation of water channels in variety of matrixes such as silicates, carbonates, phosphates and memebranes where for example there may be an analogy with capilliaries in bone. Clearly because we are interested in detailed data on the protons and deuterons the best technique is to use neutron diffraction.
