Crystallization of some similar organic cobaltammines
Abstract
When crystallization is accelerated by cooling the initially heated solution, the crystals of these compounds begin to take on an increasingly needle-like appearance. The crystals of the iodide compound are so small (no more than 1/2 mm in length) that their goniometric study seems extremely difficult and I preferred not to do it, especially since this compound very easily decomposes in solution. Crystals of the chloride compound have already been described earlier. However, after the final clarification by E. S. Fedorov of the principles of correct installation, the symbols of the faces of these crystals should be changed according to the transition determinant (see article).
