Stability of argon, krypton and propane clathrate hydrates of cubic structure II (CS-II) and of empty CS-II hydrate lattice has been investigated in a wide range of temperatures and pressures up to boundaries of absolute stability. The boundaries of mechanical stability in the framework of lattice dynamics method are determined in the quasiharmonic approximation from the Born stability conditions of crystal lattice. It has been shown by comparison of chemical potentials for empty hydrate lattices of structures I and II and ice Ih that at positive pressures empty hydrate lattices are thermodynamically metastable regarding to the ice Ih. At negative pressures there exist equilibrium lines between these phases. It has been found that despite weakness of the guest–host interactions, the guest molecules stabilize metastable host framework and the boundaries of stability depend on the type of the guest molecule. Moreover, in the cases of argon and krypton hydrates, the effect of double occupancy of the large cage on stability of CS-II structure has been also examined.

The structure and composition of (n-Bu)4NF·5.5H2O hydrate were determined from single crystal X-ray diffraction data at 173 K. It is monoclinic C2/c with cell parameters a=16.590(3), b=17.040(3), c=16.510(3) Å, β=103.18(3)°. Water molecules and fluorine ions connected by hydrogen bonds form cages consisting of two square faces and four pentagonal faces. These cavities are connected to each other, forming an infinite chain parallel to the c axis of the crystal.

The solved structures of clathrates between 1,1′-binaphthyl-2,2′-dicarboxylic acid (BNDA) as host and acetic, propionic and butyric acid guests together with previously determined clathrates of BNDA with formic and acetic acid testify that each of the first four representatives of the homologous series of aliphatic monocarboxylic acids has its own association mode with the dicarboxylic host. Acetic acid forms a clathrate specific for it at room temperature and gives a solvate isostructural with the propionic acid inclusion complex at 60°C. The host–guest complex of butyric acid is isostructural with the clathrate of valeric acid. As a matter of principle, it is shown that (1) the larger the monocarboxylic acid molecule the greater is its ability to disintegrate infinite chains of H-bonded host molecules characteristic for a guest-free host compound—formic acid is not able to cut host chains to smaller fragments and attaches itself to them, acetic acid tends to cut chains to dimers which are then associated to circular tetramers through H-bonds of guest molecules, propionic acid disintegrates host chains to linear tetramers while butyric as well as valeric acid cut the chains to dimeric units. (2) The higher the crystallization temperature of the dicarboxylic host from solutions in acetic acid the stronger is the interaction between the host molecules in the obtained crystal modification.
