In the title complex, [Cu(C(12)H(15)Cl(2)N(2)O)(2)], the Cu(II) ion is coordinated by one N,O-bidentate and one N,N',O-tridentate Schiff base ligand, resulting in a distorted CuN(3)O(2) square-based pyramidal coordination for the metal ion, with the O atoms lying trans to each other in the basal plane.

The synthesis of a new tridentate Schiff-base thiosemicarbazone ligand (HL) that derived from the reaction ((R)-2-((4-(dimethylamino)phenyl)((2-nitrophenyl)amino)methyl)-5,5-di methyl- cyclohexane-1,3-dione with thiosemicarbazide is reported. title ligand(E)-2-((R)-2-((R)-(4-(dimethylamino)phenyl)((2-nitrophenyl)amino)methyl)-5,5-dimethyl-3-oxocyclohexylidene)hydrazine-1-carbothioamide selected...

Two new unsymmetrical N-heterocyclic carbene ligand (uNHC)-based ruthenium complexes featuring phenolic OH function were obtained and fully characterised. The more active one was then immobilised on the metal–organic framework (MOF) solid support (Al)MIL-101-NH2. catalytic activity of such a heterogeneous system tested, showing that, while catalyst is less than corresponding homogeneous in solu...

Simple amine and diamine derivatives can promote the palladium catalysed direct β-C-H arylation of aliphatic aldehydes via transient imine formation. Trifluoroacetate was shown to be crucial in promoting the reaction. Sub-stoichiometric quantities of simple N-tosylethylenediamine was shown to form a bidentate directing group with an imine linkage. Isolation of an unsymmetrical palladacycle has ...

The tridentate ligands E(CH2CH2OPiPr2)2 (E = NH 1, E = S 2) were employed in the synthesis of a number of ruthenium complexes. Reaction of these ligands with (Ph3P)3RuCl2 afforded the dimers [Ru(HN(CH2CH2OPiPr2)2)Cl(μ-Cl)]2 (3) and [(Ru(E(CH2CH2OPiPr2)2))2(μ-Cl)3][X] (E = NH, X = PF64, E = S, X = Cl 5), respectively. Using (Ph3P)3RuHCl in reactions with 1 gave Ru(NH(CH2CH2OPiPr2)2)(PPh3)HCl (6)...

The synthesis, structure and photophysical properties of two polynuclear zinc complexes, namely [Zn6L2(µ3-OH)2(OAc)8] (1) [Zn4L4(µ2-OH)2](ClO4)2 (2), supported by tridentate Schiff base ligand 2,6-bis((N-benzyl)iminomethyl)-4-tert-butylphenol (HL) are presented. synthesized compounds were investigated using ESI-MS, IR, NMR, UV-vis absorption spectroscopy, photoluminescence spectroscopy single-c...

The organotin(IV) compounds, [Ph3SnL H]n Æ nCCl4 (1), [Me2SnL (OH2)] (2), [ Bu2SnL ] (3), [Ph2SnL ]n (4), [Ph3SnL H]n (5) and [Ph3SnL H]n (7) (L 1 = 2-{[(2Z)-(3-hydroxy-1-methyl-2-butenylidene)]amino}phenylpropionate and L 3 = 2-{[(E)-1-(2-hydroxyaryl)alkylidene]amino}phenylpropionate), were synthesized by treating the appropriate organotin(IV) chloride(s) with the potassium salt of the ligand ...

Rhodation of trimethylene-bridged diimidazolium salts induces the intramolecular activation of an alkane-type C-H bond and yields mono- and dimetallic complexes containing a formally monoanionic C,C,C-tridentate dicarbene ligand bound to each rhodium centre. Mechanistic investigation of the C(alkyl)-H bond activation revealed a significant rate enhancement when the carbene ligands are bound to ...

Herein, we present (E)-selective transfer semihydrogenation of alkynes based on an iridium complex in situ generated from [Ir(COD)Cl]2 and unsymmetrical (bearing two different phosphorous centers), ferrocene-based phosphine ligand utilizing formic acid as a hydrogen donor. Interestingly, ligand-to-metal ratio may be used to control the stereoselectivity process: 1:1 led formation (Z)-alkene maj...
