Approaches to Crystal Formation and Growth

Why Do CoC12-4H20 Crystals Form Very Slowly and CoC12-2H20 Crystals Readily Convert to CoC12-6H20 upon Cooling  

In aqueous chloride solution, cobalt(II) forms octahedral [Co(H20)6]2+, [CoC1(H20)5] +, and [CoC12(H20)4]° and tetrahedral [CoC13(H20)] and [CoCl4]2- complexes (36-42). With an increase in temperature, the formation of higher complexes is enhanced, because the enthalpies of formation of the complexes, AH° (n = 1-4), are all positive (43). 

Cobalt(II) dichoride di-, tetra-, and hexahydrate crystals form over the temperature range 58°C, 58-49°C, and 49°C, respectively. The 

Why Is the Hydrate Melt of CaCl2 i H20 with R = 6 Easily Supercooled but Hydrate Melts with R = 4 and 8.6 Are Not  

Some liquids can be supercooled when the temperature is decreased. It is easily supposed that a liquid-solid equilibrium might be achieved quickly when the molecular arrangement of a liquid is similar to that in the solid, which should be in equilibrium with the liquid at the
