A series of dn transition metal coordination complexes: Structures and comparative study of surface electron behaviors (n=9, 8, 7, 6, 5)

“…The aromatic polycarboxylate ligands containing two or more carboxyl groups can form the complexes with diverse structures due to their various bridging modes and strong coordination tendency with transition metals. In the recent years, a large number of coordination complexes with aromatic polycarboxylate ligands have been reported, such as the complexes containing 1,4-benzenedicarboxylate acid [16,17], 1,3,5-benzenetricarboxylate acid [18,19] and 1,2,4,5-benzenetetracarboxylate acid [20,21]. As building blocks, the heterocyclic carboxylic acids (pyridine-, pyrazole-, and imidazole-carboxylic acids) have been used in the construction of coordination polymers.…”

“…More and more investigations have paid attention to the coordination polymers containing asymmetric rigid benzene polycarboxylate acids, such as 1,2,4-benzenetriacid [2], 1,2,3-benzenetricarboxylic acid (H 3 BTB) [3]. There are at least three structural features of the asymmetric ligands.…”

Thermal, solution and structural studies of a 3D Ag(I) coordination polymer with various Ag-Ag bonds, [Ag3(μ-Hbtc)(μ-H2btc)]n

“…The two carboxylic groups of the 'H 2 btc -' ligand act in the bi-and unidentate modes (Scheme 1, right). These coordination modes are quite different from other compounds containing this ligand [15][16][17].…”

“…Aromatic polycarboxylate acids are powerful ligands for the construction of porous frameworks with applications in guest molecule exchange [14]. Many investigations have paid attention to the coordination polymers containing asymmetric rigid benzene polycarboxylate acids, such as 1,2,3-benzenetricarboxylic acid (H 3 btc) [15][16][17], 1,4-benzenedicarboxylic acid [18,19], 1,3,5-benzenetricarboxylic acid [20][21], and 1,2,4,5-benzenetetracarboxylic acid [22][23][24]. In this work we report the reaction of benzene-1,3,5-tricarboxylic acid (H 3 btc) with silver(I) nitrate and crystal structure, thermal behaviors and solution studies of the resulting coordination polymer.…”
