Figure 8
The structure of [Cu2(Hhba)4(H2O)2]·2(Et4NNO3) (6), showing (a) the hydrogen bonding from four phenolic groups to a pair of nitrate anions, and from water molecules to pairs of phenolic groups, and (b) the 2D network. Hydrogen bonds are indicated by black and white striped connections, whilst close interionic contacts between nitrate anions are indicated by pink and white striped connections. Only a single orientation of each of the disordered Et4N+ units is represented in part (b). |
