Using the HETPHEN concept a general and quantitative approach to the formation of heteroleptic nanogrids is illustrated.
Reactions of Cp*(2)Zn(2) with sterically demanding bis(iminodi(phenyl)phosphorano)methanes LH (LH = CH(2)(Ph(2)P=NR)(2) (R = Ph L(1)H, SiMe(3)L(2)H, 2,6-i-Pr(2)C(6)H(3) (Dipp) L(3)H) at ambient temperature occurred with elimination of Cp*H and subsequent formation of the homoleptic complex L(1)(2)Zn(2)1 and the heteroleptic complexes LZnZnCp* (L = L(2)2, L(3)3, L(1)4). 3 is the first structural...
Fine tuning of the electronic properties a series homo- and heteroleptic Ru(ii) complexes.
A series of new heteroleptic and homoleptic Ru(II) complexes containing variously substituted bis(pyridyl)triazine ligands has been prepared and their absorption spectra, redox behaviour and luminescence properties (both in fluid solution at room temperature and in a rigid matrix at 77 K) have been investigated. For some compounds, X-ray structures have also been determined. The new bis(pyridyl...
The stabilizing and destabilizing mechanism in the action of acetylacetone on zirconium propoxide precursors is revealed; the nature of heteroleptic intermediates provides an explanation.
Heteroleptic copper complexes containing an acetylacetonato ligand and a thioether derivatized dipyrrinato ligand are shown to form oligomers and polymers in the solid state.
Amphiphilic metallo-supramolecular diblock copolymers containing either a reversible cobalt(III) or nickel(II) heteroleptic bis-terpyridine complex at the junction between a polystyrene and a poly(ethylene oxide) block have been successfully prepared.
A series of racemic 2-[(2′-(dimethylamino)binaphthyl-2-ylimino)methyl]-4-R2-6-R(1)-phenols (L1H–L6H) were reacted with 1 equiv. of Mg[N(SiMe3)2]2 or Zn[N(SiMe3)2]2 to provide three heteroleptic magnesium silylamido complexes [(L4–(6))MgN(SiMe3)2] (4a: R(1) = R(2) = cumyl; 5a: R(1) = CPh3, R(2) = Me; 6a: R(1) = CPh3, R(2) = (t)Bu) and one heteroleptic zinc silylamido complex [(L(4))ZnN(SiMe3)2] ...
Heteroleptic complexes, formed selectively by using a 1 : 1 combination of a sigma-donor and a pi-acceptor ligand, are involved in Rh- and Pd-catalysed reactions.
Homo- and heteroleptic copper(I) complexes obtained from various chelating bis-phosphine ligands and Cu(CH3CN)4BF4 have been used for the preparation of light emitting devices.
