Melting Diagram

The thermodynamical data of solid aluminium lanthanum chloride LaAlCl6 have been obtained by determination of the decomposition equilibria from total pressure measurements. The melting diagram was determined by DTA. The chemical transport of LaCl3 with AlCl3 is suggesting the existence of the gaseous complex LaAl3Cl12. The data are:ΔH(LaAlCl6f,298) =-427,1 ±2,5 kcal/mol, S°(LaAlCl6,f,298) = 61 ±2,5 cal/K-mol,Δ(LaAl3Cl12,g ,298) =-712 ± 7 kcal/mol, S°(LaAl3Cl12,g,298) = 205 ± 3 cal/K-mol.

Quasi Binary System

The melting diagram of the quasi-binary system NH3-HF between the limits NH4HF2 and HF was redetermined. The compounds NH3 · 4HF, NH3 · 5HF and NH3 · 8HF with melting points of 26, -14 (dec.) and -95 °C (dec.), respectively, were established as the stable phases. Their crystal structures were determined as those of ammonium hydrogen fluorides NH4[F(HF)4], NH4[F(HF)4] and NH4[HF2(HF)3] · 3HF with extended N-H···F and F-H···F hydrogen bonding.

Abstract The melting diagram of the system 18-crown-6/water has been set up and the existence of four binary hydrates confirmed. Crystal structures have been determined for three of these, in addition to that for the hexahydrate already published. The hydrates are monoclinic, a tetrahydrate (previously reported as a 4.5-hydrate) with space group P21/c and Z = 2 formula units per unit cell, an octahydrate with I2/a and Z = 4, and a dodecahydrate with P21/n and Z= 2. In each structure the crown ether molecule has the (pseudo) D3d conformation common for many of its complexes, and is immediately hydrogen-bonded by a group of four water molecules in a similar, characteristic pattern. In the tetrahydrate, with one of the waters disordered, the total connectivity is that of a 1D chain, while the overall structures of the octa-and dodecahydrate are 3D networks. Four of the six independent water molecules in the dodecahydrate are linked with each other into a rare 2D ice-like layer.
