Switchable Heteroleptic Mononuclear Iron(II) Complexes as Versatile Molecular Building Block

Heteroleptic N6 coordinated ruthenium(II) complexes as building blocks for the formation of discrete Ru2Ag2 complexes.

A heteroleptic N(6) coordinated Ru(II) complex acts as a building block for a discrete tetranuclear mixed metal Ru(II)(2)Ag(I)(2) coordination compound; both complexes have been structurally characterised by X-ray crystallography.

Helicates as Versatile Supramolecular Complexes.

Pyrazine as a building block for molecular architectures with PtII.

A series of pyrazine (pz) complexes containing cis-(NH(3))(2)Pt(II), (tmeda)Pt(II) (tmeda = N,N,N',N'-tetramethylethylenediamine), and trans-(NH(3))(2)Pt(II) entities have been prepared and characterized by X-ray crystallography and/or 1H NMR spectroscopy. In these compounds, the pz ligands act as monodentate (1-3) or bidentate bridging ligands (4-7). Three variants of the latter case are descr...

Heteroleptic metallosupramolecular complexes of bodipy dyes as energy transfer cassettes.

Bodipy dyes with integral phenanthroline and terpyridine units heteroleptically assemble in the presence of zinc(II) ions to form energy transfer cassettes. These discrete complexes exhibit an approach to modularly designed efficient energy transfer and light harvesting systems through metal ion coordination.

A versatile building block for pyrazole-pyrrole hybrid macrocycles.

This contribution describes the synthesis of a novel pyrazole-pyrrole building block and its use in the formation of a non-aromatic, Schiff base-type macrocycle incorporating a chromophore and H-bonding donor and acceptor functionalities inside and outside of the macrocycle, which makes it predestined for molecular recognition systems.
