The title complex, [Cu(2)(C(13)H(16)N(3)O(3))(C(12)H(8)N(2))(H(2)O)]NO(3), consists of a nitrate ion and a binuclear Cu(II) unit in which the oxamide ligand has a cis geometry, is fully deprotonated and acts in a bidentate fashion to one Cu(II) atom and in a tetradentate fashion to the other Cu(II) atom. The Cu(II) atom coordination geometries are distorted square-planar and distorted square-py...

In the title centrosymmetric binuclear Ag(I) complex, [Ag(2)(NO(3))(2)(C(12)H(10)N(4))(2)], each Ag(I) center is coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 2-(3-pyridylmeth-yl)-2H-benzotriazole (L) ligands, and an O atom of a coordinated NO(3) (-) anion in a distorted T-shaped geometry. This forms a unique box-like cyclic dimer with an intra-molecula...

In the centrosymmetric binuclear title compound, [Cu(2)(C(8)H(3)ClO(4))(2)(C(12)H(12)N(2))(2)(H(2)O)(4)], the Cu(II) ion is six-coordinated by two N atoms from a 5,5'-dimethyl-2,2'-bipyridine ligand, two bridging O atoms from two 3-chloro-benzene-1,2-dicarboxyl-ate ligands and two water mol-ecules in a distorted octa-hedral geometry. The binuclear complex mol-ecules are linked together by inter...

Three new Schiff base complexes, namely [Mn(L)Cl] H2O (1), [Co(L)Cl]2 2CH3COCH3 (2) and [Co(L)NCS]2 (3), where H2L = 2,2 0-[propane-1,2-diylbis(nitriloeth-1-yl-1-ylidene)]diphenol, have been prepared and characterized. The syntheses of 1 and 2 have been achieved by reacting equimolar amounts of the respective metal chloride and the tetradentate Schiff base ligand (H2L). While the mononuclear Mn...

Two new zinc complexes, Zn(HL1)2 (1) and [Zn2(H2L2)(OAc)2]2 (2) [H2L1 = Schiff base derived from o-vanillin and (R)-(+)-2-amino-3-phenyl-1-propanol, H3L2 = Schiff base derived from o-vanillin and 2-amino-2-ethyl-1,3-propanediol], have been synthesized and characterized by single crystal X-ray diffraction, elemental analyses, TG analyses, solid fluorescence, IR, UV-Vis and circular dichroism spe...

A number of new binuclear complexes have been synthesised by interaction of stable Ni(II) and Cu(II) metal chelates of p-Methylisonitroacetosophenone with Alkaline earth metal salts having general formula[Ma(p-MeINAP)2MbL2 or MbX2]where Ma=Ni(II) or Cu(II),p-MeINAP = deprotonated pMethyiIsonitrosoacetophenone, Mb= Ca ++ or Mg ++ ,L = deprotonated ortho amino benzoic acid and 8hydroxyquinoline X...

The binuclear cationic complex com...

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

We report the synthesis of two novel binuclear Pd–diimine catalysts and their unique behaviors in initiating “living” polymerization of ethylene and 1-hexene. These two binuclear catalysts, [(NˆN)Pd(CH2)3C(O)O(CH2)mO(O)C(CH2)3Pd(NˆN)](SbF6)2 (3a: m = 4, 3b: m = 6) (NˆN≡ArN=C(Me)–(Me)C=NAr, Ar≡2,6–(iPr)2C6H3), were synthesized by simply reacting [(NˆN)Pd(CH3)(N≡CMe)]SbF6 (1) with diacrylates, 1,...

A binuclear tungsten(0) complex with an asymmetric bridging 1,2-diphosphole ligand was prepared by the photolysis of tungsten hexacarbonyl in presence 1-isopropyl-2-phenyl-1,2,5,6-tetrahydroacenaphtho [5,6-cd][1,2]diphosphole. The 1 characterized high resolution mass spectrometry, multinuclear NMR spectroscopy (1H, 13C, 31P), and elemental microanalysis. structure trans isomer resolved single c...
