Crystal Engineering of the Coordination Architecture of Metal Polycarboxylate Complexes by Hydrothermal Synthesis: Assembly and Characterization of Four Novel Cadmium Polycarboxylate Coordination Polymers Based on Mixed Ligands

A new open framework material based on designed semi-rigid T-shaped tricarboxylate ligand

“…Single-crystal X-ray structural analysis shows that compound 1 is a 3D open framework composed of well-separated host polymer and (7) to 2.6912(7) Å and are well in the normal range [11]. As displayed in Fig.…”

Synthesis, X-ray crystal structures, and luminescent properties of two coordination polymers constructed from transition metal complexes of mixed flexible–rigid ligands

“…A lot of organic aromatic rigid polycarboxylate ligands such as 1,4-benzenedicarboxylate, 1,3,5-benzenetricarboxylate, and 1,2,4,5-benzenetetracarboxylate have been widely used in the formation of metal-organic frameworks, which results from their high symmetry and structural predictability [10,11]. Despite the rich coordination chemistry exhibited by rigid symmetry ligands, studies on flexible saturated aliphatic dicarboxylate ligands are less well reported [12,13], probably because the flexibility of the ligands makes it difficult to predict the reaction products in such cases [14,15]. The ligands have at least two intriguing structural features.…”

Coordination polymers with adamantanediacetate bridges: syntheses, structures, and magnetic properties

“…The design of coordination polymers in which metal centers are linked by organic molecules has attracted much attention because of their structural topological novelty [1][2][3][4][5][6][7] and their potential applications such as luminescence [8][9][10], molecular magnetism [11][12][13][14][15], molecular absorption [16,17], catalysis [18,19], and ionexchange [20,21]. Among these applications, molecular magnetic materials are usually prepared through a building-block approach, where the paramagnetic transition metal ions are combined with appropriate bridging ligands that allow for magnetic exchange coupling [22].…”
