The selenoureas PhC(O)NHC(Se)NPhMe, 4-MeC6H4C(O)NHC(Se)NPhMe and 4-MeC6H4C(O)NHC(Se)NEt2 were prepared and characterized by spectroscopic methods and single crystal X-ray diffraction. 4-MeC6H4C(O)NHC(Se)NEt2 was reacted with some Pt(II), Pd(II) and Ru(II) precursors to give heteroleptic, cationic metal complexes which were characterized by NMR spectroscopy, electrospray mass spectrometry and, i...

Two silylene nickel carbonyl complexes of composition L·Ni(CO)(3) (1) {L = PhC(NtBu)(2)SiCl} and L'(2)·Ni(CO)(2) (2) { L' = RSiCl(2), R = (1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene)} were prepared by reacting 1 equivalent of Ni(CO)(4) with 1 equivalent of heteroleptic chlorosilylene L for 1 and with 2 equivalents of carbene stabilized dichlorosilylene L' for 2 in toluene at room tempera...

Herein we describe the synthesis and characterization of a neutral heteroleptic iridium complex bearing an unusual 2-pyridyl-6-methylthiazine dioxide ligand (pythdo). X-ray crystallographic analysis reveals that in the complex, the pythdo ligand is twisted and puckered, resulting in very low photoluminescent quantum efficiency. The emission profile is structured. Excited state lifetime measurem...

Encapsulation makes the difference!. A β-cyclodextrin-based diphosphane ligand with metal confining properties is key in stabilization of heteroleptic Cu(I) complexes. In their Research Article (e202214638), Nicola Armaroli, Béatrice Delavaux-Nicot, Jean-François Nierengarten, Dominique Armspach et al. show how encapsulation metal-bound diimine moiety cyclodextrin cavity influences electronic p...

Binuclear dithiocarbamate complexes of Ru(III) are promising candidates in the search for outstanding metal-based anticancer agents. While different dithiocarbamates have shown ligand-dependent cytotoxicity homoleptic binuclear complexes, properties heteroleptic analogues with (DTC) ligands yet to be explored. We herein propose introduction as tunable features development improved ruthenium-bas...
