Pseudopolymorphism based on 1D metallacyclic chains constructed from an angular zwitterionic ditopic diacid organic linker

Two pseudopolymorphs based on one dimensional metallacyclic chains display crystalline-form-dependent optical properties.

Controllable assembly of Cu(ii) coordination compounds based on a flexible zwitterionic benzimidazole–dicarboxylate ligand: synthesis, structural diversity, reversible SCSC transformation and magnetic properties

The reversible SCSC transformation of a paddle-wheel cluster to a 1D linear polymer could be accomplished.

Metal-controlled structural variations of coordination architectures constructed from flexible 1H-benzimidazole-1-propionic acid

Five low-dimensional coordination polymers and a novel discrete dodecametallic cage have been obtained from appropriate transition metals in combination with a flexible bifunctional benzimidazole carboxylic acid.

Photoluminescent calcium azolium carboxylates with diversified calcium coordination geometry and thermal stability

Six new luminescent calcium coordination assemblies were successfully synthesized and characterized using bis- and tris-azolium carboxylic acid ligands.

Designed synthesis of a series of zwitterion–polyoxometalate hybrid materials for selective scavenging and photolysis of dyes

An effective strategy to immobilize both zwitterion and POM moieties into porous hybrid materials was developed. These materials demonstrate remarkable efficiency for selective scavenging and photolysis of cationic dyes from polluted water.

Coordination polymers of a multipyridyl and pyrazolyl ligand with conformational flexibility: syntheses, structures and luminescence

Eight novel coordination polymers were obtained by the coordination of a multipyridyl and pyrazolyl ligand, which shows rich conformational changes.
