Ligand control of metal nanoparticles (MNPs) is rapidly gaining importance as ligands can stabilize the MNPs and regulate their catalytic properties. Herein we report the first example of Pt NPs ligated by imidazolium-amidinate ligands that bind strongly through the amidinate anion to the platinum surface atoms. The binding was established by 15N NMR spectroscopy, a precedent for nitrogen ligan...

Neutral bidentate N-O type complexe of VO(II) has been synthesized through condensation of Dpenicillamine,(D-H2Pen), with Bis(acetylacetonate)- oxovanadium(IV),[VO(acac)2], at neutralmedium . The established schiff base(NO type) complex was characterized on the basis of IR andmass spectroscopy techniques.Besides,D-H2Pen binding behavior to[VO(acac)2] has been studiedin thermodynamic viewpoint u...

First, Schiff base iminopyridine ligands has been prepared by the condensation between primaryamines, different substituted anilines and active carbonyl group of pyridine carboxaldehyde, thenthe complexes [diiodo (3-ethylphenyl) pyridine-2-yl methylene amine] mercury(II), complex a,[dibromo (2,5-dimethylphenyl) pyridine-2-yl methylene amine] mercury(II) complex b, and[dinitrato bis-(2,6-dimethy...

In the title complex, [Ni(C(7)H(4)O(2)S)(C(26)H(24)P(2))]·CH(3)OH, the nickel(II) centre adopts an approximately square-planar geometry, with the Ni atom coordinating to the S and O atoms of the bidentate thio-salicylate ligand and the two P atoms of the chelating Ph(2)PCH(2)CH(2)PPh(2) ligand. There is hydrogen bonding between the methanol solvent mol-ecule and the carbonyl O atom of the thio-...

A series of quinoline based imidazolium salts were prepared and characterised as nucleophilic heterocyclic carbene (NHC) ligand precursors. The symmetrically saturated imidazolium salt prepared by ring closure of achiral tetradentate diquinolyl-diamine with triethyl orthoformate is a tridentate ligand and can function as pincer ligand while the two asymmetric imidazolium salts are bidentate and...

In the title dinuclear complex, [CuGd(C(20)H(22)N(2)O(4))(NO(3))(3)], the Cu(II) ion is located in the inner N(2)O(2) cavity of the Schiff base ligand and adopts a distorted square-planar geometry. The Gd(III) ion is ten-coordinate being bound to ten O atoms, four from the Schiff base ligand and six from three bidentate nitrate anions. The Cu(II) and Gd(III) ions are linked by two phenolate O a...

The structures of the first two complexes with bidentate coordination aminoguanidine Schiff base, i.e., 2-acetylpyridine-aminoguanidine (L), are reported. complex formula [Cd2Cl6(HL)2] (1) was obtained in reaction warm aqueous solutions chloride salts Cd(II), Zn(II) and ligand, while cadmium bromide ligand presence deprotonating agent as well ammonium thiocyanate resulted formation which base h...

The bidentate phosphine ligand 1,2-bis(di-tert-butylphosphinomethyl)benzene (1,2-DTBPMB) has been reported over the years as being one of, if not the, best ligands for achieving alkoxycarbonylation of various unsaturated compounds. Bonded to palladium, provides basis first step in commercial (Alpha) production methyl methacrylate well very high selectivity linear esters and acids from terminal ...

In the title compound, [ZnBr(2)(C(10)H(12)N(2))], the Zn(2+) ion is coordinated by the N,N'-bidentate Schiff base ligand and two bromode ions in a distorted tetra-hedral arrangement. The dihedral angle between the pyridine and the cyclo-propyl rings is 95.4 (8)°.

The title compound, [ZnBr(2)(C(12)H(28)N(2)Si)], is an example of a neutral coordination compound of a bidentate ligand to a metal centre with the Zn atom being coordinated by two Br and two N atoms, yielding a slightly distorted tetra-hedral coordination environment.
