The complete mol-ecule of the title complex, [Cu(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)], is generated by the application of a centre of inversion. The central Cu(2)N(2) core is a rhombus as the μ(2)-azide ligands bridge in an asymmetric fashion. Each Cu(II) atom is also coordinated by a monoanionic tridentate Schiff base ligand via the anti-cipated oxide O, imine N and amine N atoms. The resulting...

In the title complex, [Cu(C(9)H(6)N(2)O(5))(H(2)O)(2)]·2H(2)O, the Cu(II) atom has a square-pyramidal coordination environment with a tridentate N-(5-nitro-2-oxidobenzyl-idene)glycinate Schiff base ligand and a water mol-ecule in the basal plane. The apical site is occupied by an O atom from another coordinated water mol-ecule. The crystal structure is stabilized by O-H⋯O hydrogen bonds, buildi...

The new Schiff bases are synthesis from various and aldehyde and amine under magnetic stirrer method .The synthesized Schiff base were characterized by spectral techniques (UV-Spectra & IR-Spectra). And the Schiff base are yellow colour solid and having sharp melting point and insoluble in organic solvents.

The title compound, [Co(C13H9N2O2)2]·1.5C3H7NO, is formed as a neutral Co(II) complex with di-methyl-formamide (DMF) solvent mol-ecules. The Co(II) atom has a distorted O2N4 octa-hedral coordination sphere defined by two tridentate anionic Schiff base ligands with the O atoms being cis. The coordination sphere around the Co(II) atom is geometrically different from that reported for the co-cryst...

In the title compound, [Na(H(2)O)(2)]ClO(4)·[Cu(2)(C(9)H(7)NO(3))(2)(C(6)H(7)N)(2)], the Cu(II) atom is coordinated by one N atom and two O atoms from a tridentate N-salicylideneglycinate Schiff base dianion and one N atom from a 3-methyl-pyridine ligand. Longer Cu⋯O contacts [2.680 (2) Å] complete an approximate square-based pyramidal coordination geometry around Cu(II), forming a dimeric comp...

A new dinuclear complex, [Ni(2)(H(2)O)L(4)].5H(2)O, consisting of chelating bidentate and bridging tridentate coordinated 2-[(4-methylphenylimino)methyl]-6-methoxyphenol (HL) Schiff base ligands and water molecules has been synthesized using a traditional method. The structure of this complex was characterized by FTIR and UV/Vis spectroscopy and thermogravimetric analyses (TG-DTG) and further c...

A novel Schiff base (Z)-4-(((2-hydroxy phenyl)amino)(phenyl)methylene)-3-methyl-1-phenyl-1Hpyrazol-5(4H)-one and its analogues were synthesized by condensation of 5-methyl-2-phenyl-4-substituted pyrazolin3-one with 2-amino phenol from alcoholic solution.Schiff base ligands arecharacterizedby IR, UV, NMR, elemental analysis and single crystal Xray diffraction analysis. These potential ligands ar...
