Nevertheless, it is not soluble in acidic water, which allowed Winkler to discover the element. NF3 is polar in nature. Germanium disulfide is a white powder with a certain degree of solubility in water, easily soluble in hot alkali, and soluble in concentrated hydrochloric acid. During the refinement, difference Fourier synthesis indicated a maximum peak at the 1b (0 0 ) position, which was attributed to the excess of titanium (Ti2) with a refined site occupancy about 0.017(2) leading to a decrease in the residual electronic density.
