To study the thermal stability of the complexes, thermogravi-
metric (TG) analyses were performed on polycrystalline sam-
ples in a nitrogen atmosphere with a heating rate of
10 °C·min–1 (Figure S9, Supporting Information). The TG
curve of 1 shows that the framework collapsed in the tempera-
ture range of 368–552 °C, corresponding to the release of or-
ganic components. The remaining weight of 24.51 % corre-
sponds to the percentage (calcd. 24.76 %) of zinc and oxygen
components, indicating that the final product may be ZnO. The
TG curves of 2 shows one main weight loss. No weight losses
were observed for the complex up to 342 °C; above 342 °C,
significant weight losses occurred and ended at 471 °C, indi-
cating the removal of the corresponding organic components.
The remaining weight may correspond to the final products of
ZnO (obsd. 15.18 %, calcd. 15.52 %).

Complexes 1 and 2 were synthesized under similar reaction
conditions except the anion was changed. The structural differ-
ence of 1 and 2 revealed that the anion plays an important role
in the nuclear number (from 1 to 2), in other words, the chlo-
ride atom influences the steric hindrance and structural topolo-
gies. Thus, it is a good candidate to effect changes in the crys-
tal structure. Furthermore, the long and flexible L ligand
exhibits flexibility and conformational freedom (Chart S1,
Supporting Information). This is further evidence that the se-
lection of suitable anion and organic ligands is a major strategy
to synthesize novel structure with useful properties.
