Evolution of the crystal patterns adopted by H2Tnbpz·nH2O as a response to the increased number of water molecules. (a) The pocket hydrate PITGIL (n = 1), (b) the channel hydrate (1) (n = 4) embedding 1D aqua tapes and (c) the channel hydrate (2) (n = 5) with 2D aqua layers. For (b) and (c), the infinite aqua connectivities are orthogonal to the drawing plane. |
