Figure 7
The structure of 4, showing (a) {Na(H2O)4+}n chains involving bridging water mol­ecules; intra­chain hydrogen bonding between pairs of axial water mol­ecules (shown as black and white bonds) `pinches' the O atoms in these mol­ecules together in pairs. (b) The anti­parallel slipped stacking pattern of Hhba anions and (c) the packing arrangement, viewed along the b axis. Colour code: Na yellow, car­box­yl­ate and phenolate O red, water O green, C black and H pale pink.
