Syntheses, structures and luminescent properties of two new two-fold interpenetrating 2D coordination polymers based on 4′-(4-carboxyphenyl)-4,2′:6′,4″-terpyridine

Isomers of Terpyridine as Ligands in Coordination Polymers and Networks Containing Zinc(II) and Cadmium(II)

The use of divergent 4,2′:6′,4″- and 3,2′:6′,3″-terpyridine ligands as linkers and/or nodes in extended coordination assemblies has gained in popularity over the last decade. However, there is also a range of coordination polymers which feature 2,2′:6′,2″-terpyridine metal-binding domains. Of the remaining 45 isomers of terpyridine, few have been utilized in extended coordination arrays. Here, we provide an overview of coordination polymers and networks containing isomers of terpyridine and either zinc(II) and cadmium(II). Although the motivation for investigations of many of these systems is their luminescent behavior, we have chosen to focus mainly on structural details, and we assess to what extent assemblies are reproducible. We also consider cases where there is structural evidence for competitive product formation. A point that emerges is the lack of systematic investigations.

Synthesis, structure and properties of a new three-dimensional interpenetrated metal–organic framework with 3,3′-azodibenzoic acid (H2azdc) and 1,4-bis(1H-imidazol-1-yl)butane (bimb): {[Cd(azdc)(bimb)2]·H2O}n

A new three-dimensional interpenetrated CdII–organic framework based on 3,3′-azodibenzoic acid [3,3′-(diazenediyl)dibenzoic acid, H2azdc] and the auxiliary flexible ligand 1,4-bis(1H-imidazol-1-yl)butane (bimb), namely poly[[bis[μ2-1,4-bis(1H-imidazol-1-yl)butane-κ2N3:N3′][μ2-3,3′-(diazenediyl)dibenzoato-κ2O:O′]cadmium(II)] monohydrate], {[Cd(C14H8N2O4)(C10H14N2)2]·H2O}n, (1), was obtained by a typical solution reaction in mixed solvents (water andN,N′-dimethylformamide). Each CdIIcentre is six-coordinated by two O atoms of bis-monodentate bridging carboxylate groups from two azdc2−ligands and by four N atoms from four bimb ligands, forming an octahedral coordination environment. The CdIIions are connected by the bimb ligands, resulting in two-dimensional (4,4) layers, which are further pillared by the azdc2−ligands, affording a threefold interpenetrated three-dimensional α-Po topological framework with the Schläfli symbol 41263. The thermal stability and solid-state fluorescence properties of (1) have been investigated.
