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...

In the title benzil-idene Schiff base molybdenum(VI) complex, [Mo(C(15)H(12)N(2)O(3))O(2)(CH(3)OH)], the Mo(VI) ion is coordinated by two oxide O atoms and by two O atoms and one N atom of the tridentate N'-(3-meth-oxy-2-oxidobenzyl-idene)benzo-hydrazidate (L) Schiff base ligand. The methanol O atom completes the distorted octa-hedral configuration of the Mo(VI) atom. Strong O-H⋯N hydrogen bond...

The title complex, [ZnBr(2)(C(13)H(20)N(2)O(2))], is a mononuclear zinc(II) compound derived from the zwitterionic form of the Schiff base (E)-2-eth-oxy-6-((3-(methyl-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 bromide ions, in a tetra-hedral coordination geometry. Adjacent mol-ecules are linke...

In the monomeric dinuclear title complex, [CuSm(C(20)H(22)N(2)O(4))(NO(3))(3)], the four-coordinate Cu(II) ion has a square-planar geometry involving two O atoms and two N atoms of the deprotonated Schiff base ligand. The Sm(III) ion is ten-coordinate, chelated by four O donor atoms of the Schiff base and two O atoms each from three bidentate nitrate groups, one of which is disordered over two ...

The title dinuclear copper(II) complex [Cu2(C18H16Br2N2O4S2)2] was prepared by direct synthesis of a dianionic Schiff base derived from 5-bromo-salicyl-aldehyde and cyste-amine. The discrete mol-ecules lie across inversion centers and crystallize with two di-methyl-formamide (DMF) mol-ecules of crystallization. The unique CuII ion is four-coordinated by two tetra-dentate Schiff base ligands in ...

In the title complex, [Cu(NCS)(2)(C(12)H(19)N(3))], the Cu(II) atom is five-coordinated in a square-pyramidal geometry defined by one pyridine N, one imine N, and one amine N atom of the tridentate Schiff base ligand and two N-bonded thio-cyanate ions (one of the latter occupying the apical site). The three bridging C atoms and the two terminal C atoms of the Schiff base are disordered over two...

Metal complexes of Cu (II), Co (II), Ni (II) and Zn (II) of Schiff based derived from 5-chloro-2hydroxybenzaldehyde and 4-nitobenzenesulfonamide have been prepared and characterized on the basis of physical characteristics, micro-analytical data, H NMR, FTIR and UV spectrum data. The spectrum data confirm 1 coordination of Schiff base with metal through imine nitrogen and oxygen atom. These met...

The title cocrystal, 0.796C(19)H(16)N(4)·0.204C(18)H(14)N(4), is a disordered mixture of two potentially bidentate Schiff base ligands. The difference in the two components of the cocrystal is the replacement of the methyl group in the linkage between the imine N atoms in the major component of the Schiff base ligand by an H atom. The imino (C=N) functional groups are coplanar with the benzene ...

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...
