Detail of (I), showing an [010] stack of alternating cation pairs and anions. Colour key: Co(H2O)2Cl4 octahedra purple, Cl atoms green, C atoms blue, N atoms yellow, and H atoms grey (all radii arbitrary). The intramolecular H⋯O, other H⋯O, H⋯Cl portions of the hydrogen bonds and the pseudo-π–π-stacking contacts (see text) are coloured light blue, orange, yellow, and purple, respectively. |
