摘要

Two new organic–inorganic hybrid compounds, tri­ethyl­ene­tetra­ammonium hexa­chlorido­stannate (IV) dichloride dihydrate, (C6H22N4)[SnCl6]Cl2·2H2O, (I), and 1,4-bis­(2-ammonio­eth­yl)piperazin-1,4-diium hexa­chlorido­stannate (IV) dichloride dihydrate, (C8H24N4)[SnCl6]Cl2·2H2O, (II), have been synthesized from the same starting materials. In each case both the cations and anions are located about inversion centers. Their crystal structures exhibits alternating inorganic and organic stacking sheets in (I) and layers in (II), with Cl ions and water mol­ecules occupying the space in between. The cohesion of the three-dimensional frameworks are governed by N—H⋯Cl, N—H⋯O, C—H⋯Cl and O—H⋯Cl hydrogen bonds. Hirshfeld surface analysis of both crystal structures indicates that the H⋯Cl/Cl⋯H contacts exert an important influence on the stabilization of the packing.
