Abstract
Abstract Four 4,4′-bipyridine α,ω-dicarboxylate coordination polymers Cu(bpy)(C5H6O4) (1), Zn(bpy)(C5H6O4) (2), Zn(bpy)(C6H8O4) (3) and Mn(bpy)(C8H12O4) · H2O (4) have been synthesized and structurally characterized by single crystal X-ray diffraction methods (bpy = 4,4-bipyridine, (C5H6O4)2− = glutarate anion, (C6H8O4)2− = adipate anion, (C8H12O4)2− = suberate anion). Their crystal structures are featured by dimeric metal units, which are co-bridged by 4,4′-bipyridine ligands and dicarboxylate anions such as glutarate, adipate and suberate anions to generate 2D layers with a (4,4) topology in 1, 2 and 4 as well as to form 3D frameworks in 3. Two 3D frameworks in 3 interpenetrate with each other to form a topology identical to the well-known Nb6F15 cluster compound. Over 5–300 K, the paramagnetic behavior of 4 follows the Curie–Weiss law χm(T − Θ) = 4.265(5) cm3 mol−1 with the Weiss constant Θ = −6.3(2) K. Furthermore, the thermal behavior of 3 and 4 is also discussed.
