in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4...

The title compound, [Cu(2)(C(31)H(30)Cl(2)N(4)O(4))Cl(2)]·CH(3)CN, was synthesized by cyclo-condensation between N,N'-bis-(2-fur-yl)-N,N'-bis-(3-formyl-5-chloro-salicylaldehyde)ethyl-enediamine and 1,3-diamino-propane in the presence of Cu(II) ions. It is an unsymmetrical dinuclear Cu(II) complex. The coordination geometry for each Cu(II) atom can be discribed as distorted square-pyramidal. The...

Due to the lack of a proper imaging approach, a veracious pH map of normal and abnormal cell is still rare. In this work, we presented a rhodamine-salicylaldehyde combination (Rh-SA2) as a novel pH probe, which has dual sensitive units for both acidic and basic environment. This dual sensitive probe acts like a chameleon in living cells and offers the doubling guarantees for endocellular pH map...

The title compound, C(13)H(8)BrCl(2)NO, was obtained by reaction of 3-bromo-5-chloro-salicylaldehyde and 2-chloro-benzenamine in methanol. The mol-ecule displays an E configuration with respect to the imine C=N double bond. The dihedral angle between the two benzene rings is 4.57 (11)°. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. In the crystal structure...

The title compound, [Zn(C(13)H(16)BrN(2)O(2))I(CH(3)OH)], is a new mononuclear zinc(II) complex synthesized by the reaction of equimolar quanti-ties of 5-bromo-salicylaldehyde, 2-morpholinoethyl-amine and ZnI(2) in methanol. The Zn atom is four-coordinate in a distorted tetra-hedral geometry, binding to a phenolate O and an imine N atom of the Schiff base ligand, the O atom of a methanol mol-ec...

Single crystals of the title compound, C(16)H(14)N(2)O(5)·H(2)O, were obtained from a condensation reaction of 1,3-benzodioxole-5-carbohydrazide and 3-methoxy-salicylaldehyde in a 95% ethanol solution. The asymmetric unit consists of a Schiff base mol-ecule, which assumes an E configuration with respect to the C=N bond, and a water mol-ecule of crystallization. The dihedral angle between the tw...

Mixed ligand complexes of transition metal ions such as Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) have been synthesized using 4-(Benzeneazo)salicylaldehyde, 2-amino-4-nitrophenol and nitrates of respective metal ions. The synthesized complexes have been characterized with infra red (IR), electronic, and H-NMR Spectra, molar conductance and magnetic susceptibility measurements at room t...

The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a ...
