In coordination chemistry, the simplest supramolecular architecture is the two-metal-center
helicate. 1 As a result of a spontaneous, self-assembling process in which ligands wrap …

Siderophores are microbial iron transport agents that are produced when the organism is
iron deficient. Their medical significance is due to iron being a limiting nutrient to bacterial …

A series of dinuclear M (III)(M= Fe or Ga) catecholate complexes has been prepared using
bisbidentate catecholate ligands (L). The products contain discrete, dinuclear M2 (L) 36 …

Transition-metal helicates have played a central role in supramolecular chemistry for many
years.[1–3] The synthetic approach to these structures typically follows a twostep process: 1) …

Steric control of the formation of dinuclear double helicate and dinuclear meso -helicate
assemblies - Chemical Communications (RSC Publishing) DOI:10.1039/C3CC44611E Royal …

The synthesis of the linear tris [terpyridine] 1 with three tridentate binding sites is described.
The reaction with metal ions of octahedral coordination geometry, such as FeII or NiII, leads …

The rational design of polynuclear helicates is one of the major achievements of
metallosupramolecular chemistry.[1] These linear structures form by self-assembly and …

Silver (I) coordination is investigated for three ligands of the pyridine-azine class, in which
two pyridylimine binding units are linked directly through the imine nitrogen atoms. 1H NMR …

The bis-bidentate bridging ligand L reacts with Ag (I) ions to form a conventional dinuclear
[Ag2L2] 2+ double helicate; individual double helicate units assemble via Ag⋯ Ag …

The condensation of 5-chlorocarbonyl-2, 2′-bipyridine with a variety of rigid aromatic
diamines, L, gave a series of new bisamido-2, 2′-bipyridine based ligands (L= 4, 4 …
