PXRD patterns of pristine and water-treated (a) AEPz-SnS-1 and (b) trenH-SnS-1. The positions of the (100) and (002) peaks of the pristine samples are shown. The peak at 0.86 Å−1 corresponds to (102). The calculated patterns are based on the crystal structure of trenH-SnS-1 (Filsø et al., 2017BB7). Peaks from a minor SnO2 impurity are observed at 1.88 and 2.38 Å−1 in the 20 and 60 min trenH-SnS-1 samples. The same batch of trenH-SnS-1 was used for preparation of all samples presented in Figs. 2[link](b) and 2[link](d), and the SnO2 peaks are barely observable except for samples with low thio­stannate crystallinity, i.e. 20 and 60 min trenH-SnS-1 (see Figs. S1b and S6). PDFs of pristine and water-treated (c) AEPz-SnS-1 and (d) trenH-SnS-1.
