Figure 12
Structural representations of PZMOF. (a) Asymmetric unit showing four zinc atoms and three protocatechuic acid molecules. (b) Unit cell viewed along the a axis, with voids occupying approximately 27% of the unit-cell volume, depicted in yellow. (c) View along the b axis showing the water molecules in the channels and the different coordination geometry of the zinc atoms, represented as polyhedra. (d) View along the c axis, illustrating the overall framework structure. Hydrogen atoms have been omitted for clarity. |
