Synthesis and structure of new 2,6-(diphenylphosphinomethyl)pyridine ruthenium(II) complexes

Palladium carbene complexes as persistent radicals

“…5b,15 However, the g -factor increases slightly from 5 ( g = 2.0100) to 3 ( g = 2.0105), and to 2 ( g = 2.0110). No hyperfine structure was resolved for [PC˙(sp 2 )P]PdBr and [PC˙(sp 2 )P]PdI, but dilute solutions of [PC˙(sp 2 )P]PdCl display a well-resolved hyperfine splitting (Fig.…”

“…EPR spectroscopy indicates that all three radical species, [PC˙(sp 2 )P]PdI ( 2 ), [PC˙(sp 2 )P]PdBr ( 3 ), and [PC˙(sp 2 )P]PdCl ( 5 ) display g -factors close to 2, supporting the radical state of the backbone. 5b , 15 However, the g -factor increases slightly from 5 ( g = 2.0100) to 3 ( g = 2.0105), and to 2 ( g = 2.0110).

Pincer Complexes Based on Phosphinoaminopyridines: Synthesis, Structural Characterization and Catalytic Applications

“…PNP tridentate systems allow meridional coordination to the metal centre, where the C 2 symmetrical environment of the ligand may be maintained in octahedral catalytic intermediates [28]. This location allows the substrate to access and bind along the C 2 axis, thus interacting directly with the substituents on the phosphorus donor atoms and experiencing the quadrant effect.…”

Synthesis and solution studies of ruthenium(II) complexes with thiazole and antileukaemic drug thiopurines. Crystal structure of trans-dichlorotris(1,3-thiazole)(triphenylphosphine)ruthenium(II) ‡

“…The suspension was filtered and the solid dried under vacuum for 2 h. The extraction with ether was repeated two times. Finally the red solid was recrystallized from methanol-ethyl acetate (1 : 7 v/v), filtered and stored under vacuum for 24…”
