Figure 2 . A view of a supramolecular chain in (I), aligned along the a axis, whereby the tri-molecular aggregates sustained by O–H⋯O hydrogen bonds (orange dashed lines) illustrated in Fig. 1, are connected via N–H⋯O hydrogen bonds (blue dashed lines). Colour code: Sn, orange; Cl, cyan; O, red; N, blue; C, grey; and H, green. |
