The dehydration of TlB 5 O 6 (OH) 4 • 2H 2 O leads to a loss of water in one step, forming anhydrous TlB 5 O 8 , which is amorphous to X-ray diffraction. This can be explained by structural considerations; a decrease in oxygenated coordination of thallium ions occurs during the heating. TlB 5 O 8 cr
