“…In recent years, great efforts have been devoted to the design and synthesis of complexes with aromatic polycarboxylate ligands and transition metals, [1][2][3] as carboxylates have various coordination modes and strong coordination tendency with transition metal ions. A large number of complexes with aromatic polycarboxylic acids have been reported, such as the complexes based on 1,2-benzenedicarboxylic acid (o-H 2 bdc), 1,3-benzenedicarboxylic acid (m-H 2 bdc), 1,4-benzenedicarboxylic acid (p-H 2 bdc), [4][5][6] 1,3,5-benzenetricarboxylic acid (H 3 btc), [7][8][9][10] 1,2,4-benzenetricarboxylic acid (H 3 btc), [11] and 1,2,4,5-benzenetetracarboxylate acid (H 4 btec).…”
