diffraction. Complexes 1 - 3 adopt the 3,5-connected 2D nets with the 42.67.8}42.6}-3,5L2 topology, whereas 4 shows a 1D column with the 2,4C6 topology and 5 exhibits a 2D double layer with the hexagonal channels and the 3,4,4L35 topology, indicating the significant effect of the cocrystallized solvent molecules on the structural diversity of 4 and 5. Moreover, complex 5 can be transformed to 4 irreversibly
