Molybdenum–tetracarbonyl complexes with Schiff base ligands

Acta Crystallographica Section C Crystal Structure Communications, 1999
The single-crystal X-ray structure determinations of the title complexes, tetracarbonyl{2-[1-(methylimino)ethyl]-pyridine-N,N'}molybdenum(0), [Mo(C 8 H 10 N 2 )(CO) 4 ], and tetracarbonyl{2-[(methylimino)phenylmethyl]pyridine-N,N}molybdenum(0), [Mo(C 13 H 12 N 2 )(CO) 4 ], show that the molybdenum complexes exhibit distorted octahedral geometry.

Synthesis of chiral sulfonamide/Schiff base ligands

Tetrahedron: Asymmetry, 1998
Abstract We report a facile two step synthesis of chiral ligands for bonding to transition metals. The ligands are easily prepared from trans -1,2-diaminocyclohexane by reaction with sulfonyl chlorides to give amino-sulfonamide compounds. These intermediates are then condensed with salicylaldehyde derivatives to provide sulfonamide/Schiff base ...

Cadmium and tin complexes of Schiff-base ligands

Journal of Coordination Chemistry, 2011
This review highlights the structural properties and biological aspects of Schiff-base ligands of cadmium and tin derived from the azomethine group. It also presents extensive studies on syntheses, spectral, magnetic structural characteristics, and biological activities of the cadmium and tin complexes with Schiff bases, which have appeared in the ...

Ferrocene-Based Tetradentate Schiff Bases as Supporting Ligands in Uranium Chemistry

Inorganic Chemistry, 2015
Uranyl(VI), uranyl(V), and uranium(IV) complexes supported by ferrocene-based tetradentate Schiff-base ligands were synthesized, and their solid-state and solution structures were determined. The redox properties of all complexes were investigated by cyclic voltammetry. The bulky salfen-(t)Bu2 allows the preparation of a stable uranyl(V) complex, while

Formation of a silicon-containing macrocycle with a pyridoxalimine Schiff base ligand

Acta Crystallographica Section C Crystal Structure Communications, 2008
The reaction of dichlorodiphenylsilane with a polydentate Schiff base ligand derived from pyridoxal and 2-hydroxyaniline yields the macrocyclic centrosymmetric silicon compound 9,27-dimethyl-3,3,21,21-tetraphenyl-2,4,20,22-tetraoxa-8,13,26,31-tetraaza-3,21-disilapentacyclo[30.4.0.0(6,11).0(14,19).0(24,29)]hexatrideca-1(32),6,8,10,12,14,16,18,24,26,28 ...

Valence Tautomerism in a Cobalt Complex of a Schiff Base Diquinone Ligand

Inorganic Chemistry, 1998
The cobalt(III) complex of a Schiff base diquinone ligand CoIII(Cat-N-BQ)(Cat-N-SQ) undergoes an entropy-driven valence tautomeric equilibrium in solution yielding the CoII(Cat-N-BQ)2 species. This suggestion is supported by variable temperature electronic and 1H NMR spectra, as well as by solution magnetic susceptibility data.

A tetrameric neptunyl(v) cluster supported by a Schiff base ligand

Dalton Transactions, 2012
The first tetrameric cation-cation neptunyl(v) cluster, [{NpO(2)(salen)}(4)(μ(8)-K)(2)][K(18C6)Py](2), has been synthesized in non-aqueous solution from the reaction of [(NpO(2)Py(5))(KI(2)Py(2))](n) with K(2)salen and its structure determined in the solid state and in solution where the complex retains its tetrameric form.

A Series of Molybdenum(VI) Complexes with Tridentate Schiff Base Ligands

Zeitschrift für anorganische und allgemeine Chemie, 2002
Mononuclear and polynuclear dioxomolybdenum(VI) complexes with Schiff base ligands have been prepared by the reaction of [MoO2(acac)2] with salicylaldehyde (1 and 4), 2-hydroxy-1-naphthaldehyde (2 and 5) and 2-hydroxy-3-methoxybenzaldehyde (3 and 6) with addition of appropriate amine. All prepared complexes of the general formulae [MoO2LD] and [MoO2L]n
