Schiff bases and their metal complexes are very important in medicinal and pharmaceutical fields because of their wide spectrum of biological activities. Transition metal complexes derived from the Schiff base ligands with biological activity have been widely studied. A series of Ni (II) complexes were prepared by the reaction of salicyldimine with Nickel Oxide at room temperature. The chemical...

The bis(arylimino)acenaphthalene (BIAN) group of α-diimine compounds has shown promising electron sink behaviour and redox non-innocent activity as ligands to main transition metals. Here we present a series rhodium(I) iridium(I) complexes BIAN derivatives with 2,6-diisopropylphenyl (DippBIAN, DB) 2,4,6-trimethylphenyl (MesBIAN, MB), featuring various withdrawing donating ancillary ligands. cry...

The theoretical study of Mn(salen) catalysts has been traditionally performed under the assumption that Mn(acacen') (acacen' = 3,3'-(ethane-1,2-diylbis(azanylylidene))bis(prop-1-en-olate)) is an appropriate surrogate for the larger Mn(salen) complexes. In this work, the geometry and the electronic structure of several Mn(salen) and Mn(acacen') model complexes were studied using Density Function...

A new concept for the structural design of valence tautomeric (VT) metal complexes involving the formation of stable adducts of a tetracoordinate transition metal complex with a suitable bidentate redox-active ligand has been computationally studied using the DFT B3LYP*/6-311++G(d,p) method. The calculations, performed on a series of adducts of Co(II) diketonates with o-benzoquinone and its mon...

Air and moisture stable homoleptic bis(diimidazolylidine)nickel(II) complexes, ([(diNHC)(2)Ni](2+)) 3a,b and their corresponding silver(I) 4a,b and palladium(II) 5a,b complexes were synthesized and characterized by NMR and single crystal X-ray analysis. The catalytic potential of complex 3a was assessed in Mizoroki-Heck and Suzuki-Miyaura coupling reactions. In the Suzuki-Miyaura coupling react...

The first mixed phosphatetrahedranes were reported only recently and their reactivity is virtually unexplored. Herein, we present a study on di-tert-butyldiphosphatetrahedrane (1), which the dimer of tert-butylphosphaalkyne. (tBuCP)2 tetrahedron activated selectively by N-heterocyclic carbene (NHC) nickel(I) nickel(0) complexes, resulting in novel complexes featuring diverse (tBuCP)n-frameworks...
