In the title complex, [Cu(C(15)H(13)NO(4))(C(10)H(8)N(2))], the Schiff base ligand is derived from the condensation of 2-hydr-oxy-1-naphthaldehyde and l-threonine. The Cu(II) atom is five-coordinated by one N atom and two O atoms from the Schiff base ligand and by two N atoms from a 2,2'-bipyridine ligand in a distorted square-pyramidal geometry. In the crystal structure, the combination of int...

The title dinuclear complex, [EuNi(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(3)OH)(2)]·2CH(3)OH, is isostructural with its Ni(II)/Pr(III) analogue. The Ni(II) ion is coordinated by two O atoms and two N atoms of a Schiff base ligand and by two methanol mol-ecules, forming a slightly distorted octa-hedral geometry. The Eu(III) ion is coordinated by six O atoms from three chelating nitrate ligands and fou...

The title complex, [ZnI(2)(C(12)H(18)N(2)O)], is a mononuclear zinc(II) compound derived from the zwitterionic form of the Schiff base (E)-2-[(3-dimethyl-amino-propyl-imino)meth-yl]phenol. The Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand, and by two iodide ions in a tetra-hedral coordination geometry. In the crystal structure, mol-ecules are lin...

The title compound, [Cu(C(13)H(16)NO(2))(2)], is a mononuclear copper(II) complex derived from the Schiff base ligand 2-(cyclo-pentyl-imino-meth-yl)-5-meth-oxy-phenol and copper acetate. The Cu(II) atom is four-coordinated by the phenolate O atoms and imine N atoms from two Schiff base ligands, in a highly distorted square-planar geometry. The O- and N-donor atoms are mutually trans and the dih...

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

In the dinuclear salen-type title complex, [CuNa(BF(4))(C(18)H(18)N(2)O(4))(CH(3)OH)], the Cu(II) atom is chelated by two O atoms and two N atoms of the deprotonated Schiff base in a square-planar geometry. The Na atom is seven-coordinate as it is linked to four O atoms of the same Schiff base ligand, one O atom of the methanol and two tetra-fluorido-borate F atoms. The remaining two F atoms of...

In the title complex, [Cd(2)(NCS)(4)(C(13)H(19)N(3)O)(2)], the two Cd(II) ions are bridged by a pair of thio-cyanate N:S-bridging ligands around an inversion center. One terminal thio-cyanate N atom and one N,N',N''-tridentate Schiff base ligand complete a distorted CdN(5)S octa-hedral geometry about each Cd(II) atom. In the crystal, the Schiff base aromatic rings of adjacent mol-ecules are arr...
