Abstract New vanadyl(IV) complexes of tetradentate Schiff-base dianions containing one, two or three carbon atoms between the two iminato-nitrogen atoms are described. The compounds are either mononuclear or polymeric, as shown by the value of v(V=O), and depending upon the Schiff-base dianion. There is no evidence for electron delocalization along the polymeric chains. Some vanadium(III) complexes

An OLED emitter having a complex of Structure I. The complex has a tungsten (VI) center and two coordination units which are independent or connected together. Each coordination unit coordinates to the center with a nitrogen-tungsten bond and an oxygen-tungsten bond. The tungsten (VI) emitter can be used in light-emitting devices.

that these complexes adopt a distorted octahedral six-coordinate configuration formed by tetradentate Schiff base ligand and two binding oxygen atoms. Catalyticperformance of the prepared molybdenum complexes for oxidation of different olefins with tert-butyl hydroperoxide was evaluated. These complexes were found to be an efficient and selective catalyst for the homogeneous oxidation of various olefins
Abstract Three new mononuclearmanganese(III) complexes [Mn(L1)(SeCN)(DMSO)] (1), [Mn(L2)(N3)(DMSO)] (2) and [Mn(L3)(CH3OH)2]ClO4 (3) [where H2L1 = N,N′-bis((2-hydroxy-1-naphthyl)methylidene)phenyl-1,2-diamine, H2L2 = N,N′-bis((2-hydroxy-1-naphthyl)methylidene)-2,2-dimethylpropane-1,3-diamine and H2L3 = N,N′-bis(1-(1′-hydroxy-2-naphthyl)ethylidene)propane-1,3-diamine] have been prepared and characterized

the copper(II) centres. A broken symmetry (BS) computation based on density functional theory (DFT) evaluated the magnetic interaction in the complex using the (U)B3LYP level of theory in association with the basis sets LANL2DZ for the copper atoms and 6-31G** for the other atoms. The calculations showed ferromagnetic interaction between the two magneticcopper(II) centres with a magnetic coupling
