Journal ArticleDOI
Anion-templated self-assembly of tetrahedral cage complexes of cobalt(II) with bridging ligands containing two bidentate pyrazolyl-pyridine binding sites
TL;DR: Solution NMR experiments show that the central anion acts as a template for cage formation, with a mixture of Co(II) and the appropriate bridging ligand alone giving no assembly into a cage until the tetrahedral anion is added, at which point cage assembly is fast and quantitative.
Journal ArticleDOI
Coordination chemistry of tetradentate N-donor ligands containing two pyrazolyl-pyridine units separated by a 1,8-naphthyl spacer: dodecanuclear and tetranuclear coordination cages and cyclic helicates.
Stephen P. Argent,Harry Adams,Thomas Riis-Johannessen,John C. Jeffery,Lindsay P. Harding,Olimpia Mamula,Michael D. Ward +6 more
TL;DR: The tetradentate ligand L(naph) contains two N-donor bidentate pyrazolyl-pyridine units connected to a 1,8-naphthyl core via methylene spacers; L45 and L56 are chiral ligands with a structure similar to that of L( naph) but bearing pinene groups fused to either C4 and C5 or C5 and C6 of the terminal pyridyl rings.
Journal ArticleDOI
Synthesis of the new tripodal ligand tris-[3-(2′-pyridyl)pyrazol-1-yl]hydroborate, and the crystal structure of its europium(III) complex
Angelo James Amoroso,Alexander M. W. Cargill Thompson,John C. Jeffery,Peter L. Jones,Jon A. McCleverty,Michael D. Ward +5 more
TL;DR: The new tripodal ligand tris-[3-(2′-pyridyl)pyrazol-1-yl]hydroborate, comprising three N,N-bidentate chelating arms linked by the apical boron atom, has been synthesized as mentioned in this paper.
Journal ArticleDOI
Roles of Bridging Ligand Topology and Conformation in Controlling Exchange Interactions between Paramagnetic Molybdenum Fragments in Dinuclear and Trinuclear Complexes.
Vǎn Ân Ung,Alexander M.W. Cargill Thompson,David A. Bardwell,Dante Gatteschi,John C. Jeffery,Jon A. McCleverty,and Federico Totti,Michael D. Ward +7 more
TL;DR: The magnetic properties of two series of dinuclear complexes, and one trinuclear complex, have been examined as a function of the bridging pathway between the metal centers, and the sign and magnitude of the exchange coupling constant J is clearly related to both the topology and the conformation of the bridge ligand.
Journal ArticleDOI
A cyclic supramolecular complex containing eight metal ions, twelve bridging ligands, and an anion encapsulated in the central cavity
TL;DR: The reaction of the bis-bidentate ligand with cobalt (II) or nickel(II) supplements results in formation of complexes, which have a cyclic structure with one ion encapsulated in the central cavity as mentioned in this paper.
