ABSTRACT Ru(II)BT have been synthesized by the reaction between substituted bromobenzal thiosemicarbazones and precursors of ruthenium metal complexes, [RuHCl(CO)(EPh3)3] (where E = P/As). The Ru(II)BT was characterized analytical spectroscopic techniques. It confirms coordination thiosemicarbazone ligands suggest octahedral geometry complexes. is comprised a centre with bidentate ligands. s...

A series of eight Rhenium(I)-N-heterocyclic carbene (NHC) complexes of the general form [ReCl(CO)3(C^C)] (where C^C is a bis(NHC) bidentate ligand), [ReCl(CO)3(C^C)]2 (where C^C is a bis-bidentate tetra-NHC ligand) and [Re(CO)3(C^N^C)](+)[X](-) (where C^N^C is a bis(NHC)-amine ligand and the counter ion X is either the ReO4(-) or PF6(-)) have been synthesised using a Ag2O transmetallation proto...

Two new bidentate cyano ligands, DiCN-3 (2) and DEN-4 (3) (a,w-bis(2-cyanophenoxy)propane and butane, respectively), have been prepared. These ligands and the ethane analogue DEN-2 (1) react with Mn(C0)5Br to afford complexes of the composition Mr~(cO)~(DicN-n)Br (n= 2, 9; n = 3, 10; n = 4, 11). Complexes 9 and 10 appear to be mononuclear and contain 13and 14-membered chelate rings, respectivel...

Sulphur-nitrogen(SN) donor thiosemicarbazone ligand [(Z)-N-ethyl-2-(5-methyl-2-oxoindolin-3-ylidene)hydrazinecarbothioamide] and its Pt(II) complex were synthesized by condensation method. The compounds structurally characterized elemental analysis CHNS, FT-IR, NMR analysis. analyses data for the in good agreement with theoretical values. melting point of was higher than ligand, as expected. FT...

Zinc sulphate is currently used for treatment of zinc deficiency. Its uptake by the body is poor, necessitating the administration of high doses. This leads to a range of unpleasant side effects. In order to increase the bioavailability of zinc, several zinc complexes have been designed and synthesized using bidentate ligands of hydroxypyranones and hydroxypyridinones. Elemental analysis in eac...

The title complex, [Ir(C(11)H(6)F(2)N)(2)(C(9)H(8)NO(3))], consists of one Ir(III) ion, two C,N-bidentate 3,5-difluoro-2-(2-pyrid-yl)phenyl (F(2)ppy) ligands and one N,O-bidentate 3-allyl-oxypicolinate (pic-3-Oall) ligand. The Ir(III) ion is hexa-coordinated by two C atoms and two N atoms from the F(2)ppy ligands and one N atom and one carboxyl-ate O atom from the pic-3-Oall ligand, displaying ...

A copper(II) complex of the non-symmetric bidentate ligand 2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine (L1) is reported. The single-crystal X-ray structure of aqua-[aqua/chlorido-(0.49/0.51)](2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine)-copper(II) 0.49-chloride 1.51-hydrate, [CuCl1.51(C10H13N7S)(H2O)1.49]Cl0.49·1.51H2O or [(L1)Cl1.51(H2O...

The title compound, [Rh2Br2(C8H12)2(C17H32N4)], was obtained by the reaction of 3,3'-(propane-1,3-di-yl)bis-(1-isopropyl-3,4,5,6-tetra-hydro-pyrimidin-1-ium) bromide and [{Rh(cod)Cl}2] (cod is cyclo-octa-1,5-diene) in tetra-hydro-furan. The two Rh(I) atoms each have a distorted square-planar coordination environment, defined by a bidentate cod ligand, a bromide anion and one C atom of the bridg...

The zinc(II) complex [Zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = N,N-dimethyldithiocarbamate; thiram = N,N-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. Surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with Zn2+ in methanolic media to give the [Z...
