A novel 3D Cd(ii) coordination polymer generated via in situ ligand synthesis involving C-O ester bond formation

A novel 3D Cd(ii) coordination polymer {[Cd(ddpa)(2,2′-bpy)]·H₂O}_n (1) (H₂ddpa = 5,10-dioxo-5,10-dihydro-4,9-dioxapyrene-2,7-dicarboxylic acid, 2,2′-bpy = 2,2′-bipyridine) is hydrothermally synthesized in situ, and the influencing factors and mechanism for the in situ reaction are briefly discussed. The synthesis of 1 requires the formation of a new C–O ester bond. This current study confirms that metal ions and N-donor ligands play important roles in the domination of the in situ ligand from 6,6′-dinitro-2,2′,4,4′-biphenyltetracarboxylic acid (H₄dbta). Furthermore, the structure, thermal stability and photoluminescent property of 1 are also investigated.

Anion triggered and solvent assisted structural diversity and reversible single-crystal-to-single-crystal (SCSC) transformation between 1D and 2D coordination polymers

Synthesis of four new coordination polymers (CPs) 1–4 from angular ditopic ligand 2,6-bis(imidazol-1-yl)pyridine (pyim₂) and the anion triggered structural variation (1D and 2D)under different solvent conditions have been reported.

Anion dependent silver(i) complexes of pyrazine mono-N-oxide

Pyrazine mono-N-oxide reacts with silver salts to form either discrete complexes involving monodentate N-coordination or 1D coordination polymers in which the ligand acts in a N,O-bridging bidentate coordination mode.

Coordination polymers built with transition metal sulphates and angular 2,5-bis(imidazol-1-yl)thiophene (thim2): synthesis, structure and photoluminescent properties

Six new CPs, based on thim₂ and metal sulphates have been synthesised. The photoluminescence properties of CPs 1 and 3 have been investigated.
