Spontaneous ligand nitrosation and self-assembly into a pentacopper metallacrown complex

, 2017
Acetylacetonedioxime is spontaneously nitrosated in the presence of Cu(ii) nitrate; four of the nitrosated ligands and five Cu ions self-assemble into a metallacrown complex.

Relaxometric study of copper [15]metallacrown-5 gadolinium complexes derived from alpha-aminohydroxamic acids

, 2006
peer reviewedProton nuclear magnetic relaxation dispersion (NMRD) profiles were recorded between 0.24 mT and 1.4 T for lanthanum(III)- and gadolinium(III)-containing [15]metallacrown-5 complexes derived from alpha-aminohydroxamic acids and with copper(n)

Copper inverse-9-metallacrown-3 compounds interacting with DNA

Dalton Trans., 2010
Interaction of phenyl 2-pyridyl ketoxime (PhPyCNO)/X(-)"blends" (X(-) = OH(-), Cl(-), ClO(4)(-), 2,4-D) (2,4-DH = 2,4-dichlorophenoxyacetic acid) with copper perchlorate has yielded trinuclear clusters that have been characterized as inverse-9-metallacrown-3, accommodating one or two anions. The structure of the complex [Cu(3)(PhPyCNO)(3)(mu(3)-OH)(2,4-

Unprecedented hexagonal bipyramidal single-ion magnets based on metallacrowns

Chemical Communications, 2016
Two novel Ln( iii ) (Ln = Ce or Nd) complexes based on [15-MC-6] (MC = metallacrown) and phosphine oxide are reported. Both of them feature a hexagonal bipyramidal LnO 8 geometry ( D 6h ) and ...

A Mixed 3d−4f 14-Metallacrown-5 Complex That Displays Slow Magnetic Relaxation through Geometric Control of Magnetoanisotropy

, 2016
We describe the synthesis and magnetic properties of a unique mixed 3d−4f 14-metallacrown-5 complex. This is the first metallacrown family to feature μ-O and μ-OH bridges as well as to incorporate a LnIII ion into the ring.

Metallacrown ether and dinuclear complexes of platinum

, 2008
Im Rahmen der Arbeit wurde die Bildung von Platin(II/IV)-Komplexe mit N-Donorliganden untersucht. Zentrale Verbindungsklasse sind Metallakronenether des Platins (cyclische Strukturen, die Metallfragmente in einem Polyethermakroring, koordiniert über N-Donorsubstituenten an den beiden Enden einer Polyetherkette aufweisen), anorganische Analoga der ...
