HEXAAMMINE ALUMINIUM IODIDE MONOAMMINE, AND METHOD FOR ITS PREPARATION

摘要

Crystalline hexaamminealuminum iodide monoammoniate is characterized by certain X-ray diffraction lines (CuK alpha ) of the 15 strongest lines in order of decreasing intensity. Single crystals of hexaamminealuminum iodide monoammoniate crystallize in the space group Pmn21 with the lattice constants a=7.600 [ ANGSTROM ] b=13.315 [ ANGSTROM ] c=15.051 [ ANGSTROM ] alpha = beta = gamma =90 DEG and have certain atomic coordinates. Furthermore, processes for the preparation of hexaamminealuminum iodide monoammoniate by reacting aluminum, an iodine compound and ammonia or aluminum iodide and liquid ammonia are described.
