Nickel complexes of a binucleating ligand derived from an SCS pincer.
A binucleating ligand has been prepared that contains an SCS pincer and three oxygen donor atoms in a partial crown ether loop. To enable metalation with Ni(0), a bromoarene precursor was used and resulted in the formation of a nickel-bromide complex in the SCS pincer portion of the ligand. Reaction of the nickel complex with a lithium salt yielded a heterobimetallic complex with bromide bridgi...
متن کاملSynthesis and Studies of Spectral and Thermal Properties of Some Mixed Ligand Complexes of Thorium(IV) and Dioxouranium(VI) With Semicarbazones as Primary Ligand and Sulfoxide as Secondary Ligand
The present work describes the studies on the coordination behaviour of 4[N-(benzalidene) amino]antipyrine semicarbazone (BAAPS) (I), 4[N-(furfural)amino]antipyrine semicarbazone (FFAAPS) (II) and 4[N-(cinnamalidene)amino]antipyrine semicarbazone (CAAPS) (III) in presence of dimethyl sulfoxide (DMSO) or diphenyl sulfoxide (DPSO) towards Th4+ and UO22+ salts. All the complexes were isolate...
متن کاملA readily accessible PNP pincer ligand with a pyrrole backbone and its Ni(I/II) chemistry.
The novel chelating PNP pincer ligand 2,5-bis((diphenylphosphino)methyl)-1H-pyrrole (1) was prepared and its nickel coordination chemistry explored. The reaction with Ni(COD)(2) led to a diamagnetic dinuclear nickel(I) complex (4) which was also obtained by the reaction of the square planar Ni(II) complexes [(PNP-Ph(2))NiX] (X = Cl (2), X = I (3)) with Li(Et(3)BH).
متن کاملAmine, amido, and imido complexes of tantalum supported by a pyridine-linked bis(phenolate) pincer ligand: Ta-N pi-bonding influences pincer ligand geometry.
A series of tantalum imido and amido complexes supported by a pyridine-linked bis(phenolate) ligand has been synthesized. Characterization of these complexes via X-ray crystallography reveals both C(s) and C(2) binding modes of the bis(phenolate)pyridine ligand, with complexes containing two or fewer strong pi-donor interactions from ancillary ligands giving C(s) symmetry, whereas three strong ...
متن کاملStudies on Nickel(II)-Pyridoxamine-Imidazole Containing Mixed Ligand Complex Systems
The stability constants of species present in the systems Ni(II)-pyridoxamine(pym)(A) and Ni(II)-pyridoxamine(pym)(A)-imidazole containing ligands(B) [B = imidazole(him), benzimidazole(bim), histamine(hist) and L-histidine(his)] have been determined pH-metrically using the MINIQUAD computer program. The existence of the species NiAH, NiA and NiA2 was proven for the Ni(II)-pym(A)...
