Conclusions

  1. 1.

    On the basis of a crystal chemical study of crystals of 3,5-dinitro-[(N′-(5-nitrofurfuliden)] benzhydrazide, we have established that the increase in their photosensitivity is due to the new way in which the crystal hydrates are formed (with participation of dimer associates of water).

  2. 2.

    The molecules of the studied ketohydrazone are close-packed into energetically favorable shifted stacks; as a result, the stacks themselves are also close packed. The dimer water associates are located in the channels between the stacks.

  3. 3.

    We have assigned the stretching vibration bands for the four nonequivalent hydrogen atoms of the water molecules in the IR spectra. We have shown that in the water dimer, the oxygen atom forming the N-H...OH2O hydrogen bond is a stronger proton acceptor than the oxygen atom of the monomeric water molecule.
