A series of lanthanide complexes based on pyridine-3,5-dicarboxylate and succinate ligands: syntheses, structures and properties

Structural refinement and luminescent property of a novel europium(III) complex with a proton transfer compound containing 2,6-pyridinedicarboxylate and 2,6-pyridinediammonium ligands synthesized by ultrasonic method

“…The design and construction of lanthanide metal complexes have received much attention during the last two decades because of their intriguing network topologies and potential candidates for a number of applications [1][2][3][4][5][6][7][8]. As it is well known, lanthanide complexes have good luminescent properties for their high color purity with high quantum efficiency.…”

“…Another example of a mixed ligand‐based system is that containing succinate and pyridine‐3,5‐dicarboxylate (pydc), where the nature of the Ln 3+ ion, determines the dimensionality of the resultant framework . When Ln=Yb, Lu, two isostructural compounds with formula [Ln(pydc)(succ) 0.5 (H 2 O) 2 ] ⋅ 2H 2 O are obtained which correspond to the 2D‐10 structural type in Table .…”

“…Another example is that corresponding to the 3D‐11 structural type, which exhibits a formula [Ln(pydc)(succ) 0.5 (H 2 O) 3 ] ⋅ 2H 2 O and belongs to the P21/c S.G . Four oxygen atoms from three pydc ligands, two O atoms from one succinate anion and three coordinated water molecules are surrounding the Ln 3+ ion, forming a distorted tricapped trigonal prism coordination polyhedron.…”

A luminescent Terbium-Succinate MOF thin film fabricated by electrodeposition for sensing of Cu2+ in aqueous environment

“…While aliphatic dicarboxylates as a kind of cheap industrial precursors, are not very commonly being used as ligands of MOF. Among them, the succinic acid (SA) presents interesting behaviors due to their conformational flexibility and coordination diversity [38], which is commonly used as the second ligands to fortify the MOF structure [39][40][41]. Previously reported Ln-succinate complexes indicated that succinic acid is an ideal ligand to forming flexible porous structure as well as being efficient energy donor [42,43], which is a promising ligand for luminescent sensing applications, but the luminescent sensing potential of Ln-succinate complex remains unexplored.…”
