The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·H(2)O, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is almost planar (r.m.s. deviation for all non-H atoms = 0.040 Å). The amido N atom is the hydrogen-bond donor to the water mol-ecule, which is the hydrogen-bond donor to the hydr-oxy groups of two neighboring mol-ecules. One of the ...

The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·C(3)H(7)NO, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is nearly planar (r.m.s. deviation 0.20 Å). The amido N atom is a hydrogen-bond donor to the dimethyl-formamide solvate mol-ecule. One of the hydr-oxy groups forms an intra-molecular hydrogen bond to the N atom of the C=N double...

In the trinuclear title compound, [Zn(3)Cl(6)(C(13)H(20)N(4))(2)]·2H(2)O, each terminal Zn(II) atom is coordinated by an N(3) donor set from the Schiff base ligands and two Cl atoms in a distorted square-pyramidal geometry. The central Zn(II) atom is tetra-hedrally coordinated by two piperazine N atoms from two Schiff base ligands and two Cl atoms. The piperazine rings adopt chair conformations...

Coconut water (Cocos Nucifera) is shown to be a source of essential elements present in the form low-molecular weight stable complexes known for their bio-availability. The total element concentrations were range 0.2–2.7, 0.3–1, 3–14 and 0.5–2 ppm Fe, Cu, Mn, Zn, respectively, varied as function origin nut its maturity. Speciation was investigated by size-exclusion chromatography - inductively ...

The asymmetric unit of the title compound, [Sm(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], contains two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (HL) ligands, three nitrate ions and one methanol mol-ecule that binds to the nine-coordinate samarium(III) ion via its O atoms. The HL ligands chelate with a strong Sm-O(deprotonated phenolic) bond and a weak Sm-O(meth-oxy) con...

The metal center in the structure of the title compound, [Eu(NCS)(3)(C(15)H(15)NO(2))(3)], is coordinated by three Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (L) ligands and three independent thio-cyanate ions. In the crystal structure, the acidic H atom is located on the Schiff base N atom and hydrogen bonded to the phenolate O atom. The coordination environment of the...

The title compound, [Cu(2)(C(18)H(19)N(3)O(2))(2)]·2C(2)H(6)OS or [Cu(2)(SalenN(3)H)(2)]·2DMSO, where SalenN(3)H is the multidentate Schiff base 2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenolate dianion and DMSO is dimethyl sulfoxide, is a solvated dinuclear Cu(II) complex. The neutral complex is built from two Cu(SalenN(3)H) units related by an inversion center. All heteroa...

The asymmetric unit of the title compound, [Cd(2)Cl(2)(NCS)(2)(C(15)H(15)NO(2))(2)](n), contains the Schiff base 2-[(4-methyl-phenyl-imino)meth-yl]-6-methoxy-phenol (HL) ligand, one thio-cyanate and one chloride ligand coordinated to a cadmium centre. The cadmium centers are linked to each other via two thio-cyanate and two chloride bridges alternately, resulting in centrosymmetric zigzag chain...
