Abstract

In this work, we devote our effort to explore the effect of different hydrothermal reaction temperatures on the final structure in the Zn(II)-ox(oxalate)-bpy(4,4′-bipyridine) three-member system. At 180 °C, this system produces compound 1, namely Zn(ox)(bpy), which crystallizes in the orthorhombic Immm space group and shows the common sql net, whereas at 200 °C this system renders compound 2, namely Zn(ox)(bpy)2, which crystallizes in the monoclinic P21/c space group and features the highly rare mcm net. A careful investigation of the structures disclosed that between 1 and 2 the conformational isomers of bpy ligand are temperature-dependent, viz.D2h for 1 at 180 °C and C2 for 2 around 200 °C, which is responsible for the final temperature-controlled formation of 1 and 2.
