Dicopper(i) complexes with the chelating dmapm ligand [dmapm = 1,1-bis{di(o-N,N-dimetylanilinyl)phosphino}methane] have been synthesized and characterized structurally. Synthesis of the acetonitrile adduct [Cu2(μ-dmapm)(CH3CN)2][BF4]2 () has been presented and the dicopper electrophile has been used as the starting material in reaction with Group 14 heteroborates. Coordination of the closo-bora...

The novel diphenyltin(IV) compound [Ph(2)(HyFoSc)Sn] (2), where H(2)HyFoSc (1) is 3-hydroxy-2-formylpyridine semicarbazone, was prepared and characterized by vibrational and NMR ((1)H, (13)C) spectroscopy. The structure of [Ph(2)(HyFoSc)Sn] was confirmed by single-crystal X-ray crystallography. The doubly deprotonated ligand is coordinated to the tin atom through the enolic-oxygen, the azomethi...

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

Reaction of the tricarbon-yl{η(5)-[2-(dimethyl-amino)eth-yl]cyclo-penta-dien-yl}molybdenum anion and dichlorido-diphenyl-stannane affords the title compound, [MoSn(C(6)H(5))(2)Cl(C(9)H(14)N)(CO)(3)], which exhibits a four-legged piano-stool geometry with chlorido-diphenyl-stannyl ligands unperturbed by the pendant 2-(dimethyl-amino)ethyl groups. The Mo-Sn bond length [2.7584 (5) Å] and the dist...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...
