“…There has been continuous interest in the coordination chemistry of copper complexes, and much attention has been paid to the design and synthesis of Cu(I) and Cu(II) complexes [1][2][3][4][5]. These complexes have been widely used in metal organic framework materials (MOFs), luminescent materials, magnetic materials, and efficient catalysts [6][7][8][9].…”

Three copper complexes constructed with sulfur-bridged bis-pyridine ligands 2,2′-dithiodipyridine (dtdp) and di-2-pyridyl sulfide (dps), [Cu 2 (dps) 2 (H 2 O) 2 (μ-SO 4 ) 2 ]·(H 2 O) 2 (1), [Cu 2 I 2 (dps) 2 ] (2), and [Cu 4 I 4 (dtdp) 2 ] (3), have been synthesized by reaction of copper(I) iodide with dtdp under solvothermal and solution-diffusion conditions, and characterized by single crystal X-ray diffraction. The dps ligands were generated via in situ cleavage of S-S and S-C(py) bonds of dtdp. Cu ions are divalent in 1, implying involvement of the starting Cu + cations in a redox process, while the Cu ions remained univalent in 2 and 3. In 1 and 2, the dps adopted N,N-chelate coordination, in contrast to the N,Schelation of the dtdp ligand in 3. Complex 1 displays a 2-D framework linked by hydrogen bonds and was further connected into a 3-D supramolecular structure by π-π stacking interactions between adjacent layers. Complexes 2 and 3 exhibited 2-D layer structures through π-π stacking interactions. The luminescent properties of 2 and 3 were also studied in the solid state at room temperature.

“…The ν(C=N) absorptions are observed at 1607 cm -1 for complex 1 and 1618 cm -1 for complex 2. 13 The intense bands indicative of the C=O vibrations are absent in the complexes, indicating the enolization of the hydrazone ligands. The sharp bands indicative of the N-H vibrations are located at 3272 cm -1 for complex 1 and 3252 cm -1 for complex 2.…”

Two new oxidovanadium(V) complexes, [VOL 1 L] (1) and [VOL 2 L]•CH 3 OH (2•CH 3 OH), where L 1 and L 2 are the dianionic form of N'-(3-bromo-2-hydroxybenzylidene)picolinohydrazide (H 2 L 1) and 2-chloro-N'-(2-hydroxy-3-methoxybenzylidene)benzohydrazide (H 2 L 2), respectively, and L is the monoanionic form of 2-hydroxybenzohydroxamic acid (HL), were prepared and characterized by elemental analysis, infrared and electronic spectroscopy. Structures of the complexes were further confirmed by single crystal X-ray determination. The V atoms in the complexes are in octahedral coordination. The hydrazone ligands coordinate to the V atoms through the phenolate O, imino N, and enolate O atoms. The hydroxamate ligand coordinates to the V atom through the carbonyl and hydroxy O atoms. The complexes show effective antibacterial activity against B. subtilis, S. aureus and E. coli. The presence of Cl substitute group in the complex may enhance the antibacterial activity.

“…Of the various structures of metal complexes, the rational design and synthesis of polynuclear structures is an area of continuing interest in coordination and supramolecular chemistry. [1][2][3] A common strategy for the synthesis of polynuclear structures that involve manganese complexes is to choose the blocking ligand in such a way that the manganese ion remains coordinately unsaturated and thus allows bridging ligands to coordinate the Mn centers. Although many different bridging groups and transition metal ions have been employed for the construction of such species, the Mn III -N 3 system is one of the most popular among synthetic chemists.…”

A new phenolato and m 1,1,3 -azido co-bridged polynuclear manganese(III) complex has been synthesised and characterised. The structure of the complex has been confirmed by single crystal X-ray diffraction analyses. The ability of the complex to catalyse the epoxidation of styrene using PhIO or NaOCl as oxidant has been studied. Results show the catalysis to occur efficiently in the presence of PhIO and NaOCl.
