First-Row Transition Metal Bis(amidinate) Complexes; Planar Four-Coordination of FeII Enforced by Sterically Demanding Aryl Substituents

Synthesis and characterisation of magnesium complexes containing sterically demanding N,N'-bis(aryl)amidinate ligands.

Condensation reactions of carboxylic acids and anilines in the presence of polyphosphoric acid trimethylsilyl ester (PPSE) afforded a range of sterically demanding N,N'-bis(aryl)amidines, RN{C(R')}N(H)R [R = Mes (Mes = 2,4,6-trimethylphenyl), R' = Cy (Cy = cyclohexyl) L¹H; R = Dipp (Dipp = 2,6-diisopropylphenyl), R' = Cy L²H; R = Mes, R' = Ph L³H; R = Dipp, R' = Ph L⁴H; R = Mes, R' = Dmp (Dmp =...

Photo- and electro-luminescence of four cuprous complexes with sterically demanding and hole transmitting diimine ligands.

Four new cuprous complexes (1-4) containing bisphosphine and triazolylpyridine donors have been prepared in order to examine the effects of the methyl group and the carbazole appendage on photo- and electro-luminescence (PL and EL) properties. Because of their additional steric hindrance from the methyl substituent group at a 6-pyridine ring, complexes 3 and 4, compared with the methyl group fr...

Synthesis and characterisation of first row transition metal complexes of functionalized 1,2,4-benzothiadiazines.

Reaction of the novel ligand 3-(2'-pyridyl)-benzo-1,2,4-thiadiazine (L) with the transition metal chloride salts MCl2·xH2O (M(II) = Mn, Fe, Co, Cu and Zn) in a 2 : 1 mole ratio afforded the mononuclear octahedral (high spin) complexes L2MCl2 (1a-1e respectively) in which L binds in a chelate fashion via N(2) and the pyridyl N atoms. In the case of CuCl2 the intermediate 1 : 1 four-coordinate co...
