The structure and dioxygen-reactivity of copper(I) complexes R supported by N,N-bis(6-methylpyridin-2-ylmethyl)amine tridentate ligands L2R[R (N-alkyl substituent)=-CH2Ph (Bn), -CH2CH2Ph (Phe) and -CH2CHPh2(PhePh)] have been examined and compared with those of copper(I) complex (Phe) of N,N-bis[2-(pyridin-2-yl)ethyl]amine tridentate ligand L1(Phe) and copper(I) complex (Phe) of N,N-bis(pyridin-...

The new ligand, 2-acetylpyrazine-tertbutylthiosemicarbazone (APZ-tBTSC), and its Cu(II), Pd(II) Pt(II) complexes have been synthesized. This ligand coordinates to the metal ions in a tridentate monoanionic fashion forming monometallic with formula [M(APZ-tBTSC)Cl]. three [Cu(APZ-tBTSC)Cl], [Pd(APZ-tBTSC)Cl], [Pt(APZ-tBTSC)Cl] were tested for anti-proliferative biological behavior panel of seven...

The complexes of Ni (II) and Cu with β-Lactam-amoxicillin have been synthesized. structures these newly synthesized were substantiated by elemental analysis, molar conductivities, infrared, electronic absorption spectra magnetic moment measurements. On the basis analyses it has confirmed that direct reaction metal salts amoxicillin-suspension leads to formation complexes. tridentate nature liga...

In the title complex, [Ni(C8H5N5O3)(C2H8N2)(C3N2H4)]·2H2O, a tridentate 2-amino-7-methyl-4-oxidopteridine-6-carboxyl-ate (pterin) ligand, a bidentate ancillary ethane-1,2-diamine (en) ligand and a monodentate 1H-imidazole (im) ligand complete a distorted octa-hedral geometry around the Ni(II) atom. The pterin ligand forms two chelate rings. Both the en and im ligands are arranged nearly orthogo...

Metal complexes of 2,5-dicarboxamidopyrroles and 2,5-dicarbothioamidopyrroles have been structurally characterised for the first time, complementing the significant amount of work that has been reported for the analogous pyridine ligands. N,N'-Bis(3,5-dinitrophenyl)-3,4-diphenyl-1H-pyrrole-2,5-dicarboxamide forms octahedral bis(tridentate) complexes with cobalt(III) and nickel(II), where the li...

In the title compound, [Ni(C13H17NO3)(C12H8N2)(H2O)]·5H2O, the Ni(II) atom is in a distorted octa-hedral coordination environment provided by the two N atoms of one bidentate phenanthroline ligand and two O atoms and one N atom from a tridentate 2-[(2-hy-droxy-benz-yl)amino]-4-methyl-penta-noic acid (HAMA) ligand and one water mol-ecule. The complex was prepared by the reaction of nickel(II) ni...

A series of transition metal complexes of the ligand 5-bromo salicylaldehyde-2-furoic acid hydrazide have been prepared using Ti(III), Mn(III), V(III), Co(III), Fe(III), Ru(III) and Rh(III). The complexes have been characterized by elemental analyses, melting points, molar conductance, magnetic susceptibility measurement, electronic and infra red spectral studies. Based on these studies octahed...

In the title dinuclear Cd(II) complex, [Cd(2)(C(2)N(4)O(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], each Cd atom is in a slightly distorted octa-hedral coordination by two N atoms and one O atom of two 1H-tetra-zole-5-carboxyl-ate (TZC) ligands, two N atoms of a 2,2'-bipyridyl ligand and one water O atom. The TZC ligand acts in a tridentate N,O-chelating N-bridging mode to two symmetry-equivalent Cd(I...

In the title compound, [Zn(C(8)H(6)ClNO(4)S)(C(10)H(8)N(2))(H(2)O)], the Zn(II) atom is six-coordinated by two O atoms and one N atom from a tridentate Schiff base ligand and two N atoms from a chelating 2,2'-bipyridine ligand and one water mol-ecule, forming a slightly distorted octa-hedral geometry. In the crystal, O-H⋯O hydrogen bonds link pairs of complex mol-ecules into dimers. An intra-mo...

The Mo(VI) atom in the title complex, [Mo(C(11)H(13)N(3)OS)O(2)(C(2)H(6)OS)], is N,N',O-coordinated by the dianionic tridentate ligand, two mutually cis oxide O atoms and a dimethyl sulfoxide O atom, defining a distorted octa-hedral N(2)O(4) donor set. The most prominent feature of the crystal packing is the formation of inversion dimers via pairs of N-H⋯O hydrogen bonds and eight-membered {⋯HN...
