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 appears extremely difficult, and I preferred not to perform it, especially since this compound decomposes very easily in solution. The crystals of the chloride compound have already been described earlier. However, after E. S. Fedorov's final clarification of the principles of correct orientation, the face symbols of these crystals must be changed according to the transition determinant (see the article).
