The structure of [NEt4][Cu2(Hhba)2(H0.5hba)2(CH3OH)(H2O)]·2(dioxane) (2), showing (a) the hydrogen-bonded 4-connected node, (b) the 4,4-network with the dioxane molecules and NEt4+ ions in the square cavities (only one of the two orientations of each tetraethylammonium ion is shown), and (c) the intersheet hydrogen-bond interactions involving the coordinated water/methanol molecules which extend into sheets above and below. |
