A Cobalt Supramolecular Triple-Stranded Helicate-based Discrete Molecular Cage
We report a strategy to achieve a discrete cage molecule featuring a high level of structural hierarchy through a multiple-assembly process. A cobalt (Co) supramolecular triple-stranded helicate (Co-TSH)-based discrete molecular cage (1) is successfully synthesized and fully characterized. The solid-state structure of 1 shows that it is composed of six triple-stranded helicates interconnected b...
متن کاملIron catalysed assembly of an asymmetric mixed-ligand triple helicate.
The 2-pyridinecarbaldehyde isonicotinoyl hydrazone (HPCIH) family of ligands are typically tridentate N,N,O chelators that exhibit very high in vitro activity in mobilizing intracellular Fe and are promising candidates for the treatment of Fe overload diseases. Complexation of ferrous perchlorate with HPCIH in MeCN solution gives the expected six-coordinate complex Fe(II)(PCIH)(2). However, com...

متن کاملImposition of chirality in a dinuclear triple-stranded helicate by ion pair formation.
Chirality is a fundamental property intrinsic to many supramolecular systems.2 Helical assemblies are inherently chiral, regardless of the stereotopic information contained within the individual building blocks.3-5 Metallo-supramolecular helicates, assembled from achiral ligands and metal centers, form racemic mixtures of clockwise and counterclockwise structures in which all the metal centers ...
متن کاملPartial spin crossover behaviour in a dinuclear iron(II) triple helicate.
Reported herein are the synthesis, structural, magnetic and Mössbauer spectroscopic characterisation of a dinuclear Fe(II) triple helicate complex [Fe(2)(L)(3)](ClO(4))(4).xH(2)O (x = 1-4), 1(H(2)O), where L is a bis-bidentate imidazolimine ligand. Low temperature structural analysis (150 K) and Mössbauer spectroscopy (4.5 K) are consistent with one of the Fe(II) centres within the helicate bei...
