Abstract:
The phase diagram of the system 1,10-diaza-18-crown-6–H2O has been studied; polyhydrate 1,10-diaza-18-crown-6-8.25H2O, which melts incongruently at 16.0 °C, has been found in this system. Each cavity of the three-dimensional framework made of water molecules accommodates four molecules of crown ether; the hydrate has the following crystallographic parameters: a = 18.848(2), c= 13.159(2) Å (T = −100°C), space group P42/n and Z = 8.
