Trinuclear first row transition metal complexes of a hexapyridyl, trialkoxy 1,3,5-triarylbenzene ligand.

Trinucleating copper: synthesis and magnetostructural characterization of complexes supported by a hexapyridyl 1,3,5-triarylbenzene ligand.

Trinuclear Nickel Complexes with Metal-Arene Interactions Supported by Tris- and Bis(phosphinoaryl)benzene Frameworks.

Triphosphine and diphosphine ligands with backbones designed to facilitate metal-arene interactions were employed to support multinuclear Ni complexes. Di- and trinuclear metal complexes supported by a triphosphine containing a triarylbenzene linker display diverse metal-arene binding modes. Multinuclear Ni halide complexes were isolated with strongly interacting metal centers bound to opposite...

Synthesis of New Schiff Base Ligand and Its Complexes in The Presence of Some Transition Metal Ion and Evaluation of Their Antibacterial Properties

ABSTRACT         Background and objectives: Synthesis and characterization of several metal complexes (metal ions: Co2+, Ti4+ and Ce3+) of macroacyclic Schiff base ligand have been reported. The Schiff base ligand is prepared from the condensation reaction of 1, 4-di-(4-fluoro-2-aminophenoxy) butane with salicylaldehyde in ethanol. In addition, antibacterial ...

Nitric oxide activation by distal redox modulation in tetranuclear iron nitrosyl complexes.

A series of tetranuclear iron complexes displaying a site-differentiated metal center was synthesized. Three of the metal centers are coordinated to our previously reported ligand, based on a 1,3,5-triarylbenzene motif with nitrogen and oxygen donors. The fourth (apical) iron center is coordinatively unsaturated and appended to the trinuclear core through three bridging pyrazolates and an inter...

Heterotrimetallic complexes of a phenylene-bridged tricarbene ligand.

Reaction of the benzene-1,3,5-trisimidazolium salt H3-1(Br)3 with [Rh(Cp*)(Cl)2]2 results in the formation of the dinuclear, doubly orthometalated complex [2]Br, which yields, depending on the metal source provided, either a triply orthometalated heterotrimetallic Rh2/Ir complex [3] or trinuclear heterotrimetallic Rh2/Au complexes of types [4a] or [4b].
