ABSTRACT: In the title mononuclear Schiff base complex, [Dy(NO(3))(3)(C(18)H(20)N(2)O(4))], the Dy(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra-molecular N-H?O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular C-H?O hydrogen bonds.

Project description:In the title mononuclear salen-type complex, [Eu(NO(3))(3)(C(22)H(26)N(2)O(4))]·CH(3)OH, the Eu(III) ion is ten-coordinated by three bidentate nitrate counter-ions and one organic salen-type ligand, which acts in a bis-bidentate chelating mode through its phenolate and meth-oxy O atoms. The protonated imine groups are involved in intra-molecular N-H⋯O hydrogen bonds to the phenolate O atomss, emphasizing the zwitterionic nature of the ligand. An O-H⋯O hydrogen bond links the complex and solvent mol-ecules.

[N'-(3-Meth-oxy-2-oxidobenzyl-idene-κO)benzohydrazidato-κN',O]tris-(pyridine-κN)cobalt(III) perchlorate.

Project description:In the mononuclear title compound, [Co(III)(C(15)H(12)N(2)O(3))(C(5)H(5)N)(3)]ClO(4), the Co(III) ion is coordinated by three pyridine mol-ecules and one N'-(3-meth-oxy-2-oxidobenzyl-idene)benzohydrazidate Schiff base ligand in an O,N,O'-tridentate manner. The Co(III) ion adopts a distorted CoN(4)O(2) octa-hedral coordination environment.

{1,8-Bis[2-(2-oxidobenzyl-idene-amino)phen-oxy]-3,6-dioxaocta-ne}nitrato-praseodymium(III) trichloro-methane solvate.

Project description:In the title compound, [Pr(C(32)H(30)N(2)O(6))(NO(3))]·CHCl(3), the Pr(III) ion is ten-coordinated by eight O atoms and two N atoms from the acyclic crown-type Schiff base ligand and the bidentate nitrate group. The coordination polyhedron around Pr(III) is a distorted bicapped square anti-prism. The chloro-form solvent mol-ecule is not involved either in coordination to the Pr(III) center or in hydrogen bonding to the complex. The Pr-O(phenolate) bonds are significantly shorter than the Pr-O(ether) and Pr-O(nitrate) bonds, which suggests that the Pr-O(phenolate) bond is stronger than these other bonds. In the crystal structure, the acyclic crown-type Schiff base ligand wraps around the Pr(III) centre, forming a pseudo-ring.

Project description:In the title mol-ecule, C(19)H(22)N(4)O(2)S, the two benzene rings form a dihedral angle of 9.16?(13)°. In the crystal, pairs of weak inter-molecular C-H?S hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked through weak C-H?O inter-actions into sheets parallel to (012).

Hexaaqua-cobalt(II) bis-{[N-(4-meth-oxy-2-oxidobenzyl-idene)glycylglycinato]nickel(II)} hexa-hydrate.

Project description:In the title compound, [Co(H(2)O)(6)][Ni(C(12)H(11)N(2)O(5))](2)·6H(2)O, the Ni(II) atom has a nearly square-planar coordination with two N and two O atoms of the N-(4-meth-oxy-2-oxidobenzyl-idene)glycylglycinate Schiff base ligand (L(3-)). The Co(II) atom sits on an inversion center and is coordinated to six aqua ligands in a slightly distorted octa-hedral geometry. The [Co(H(2)O)(6)](2+) cations and [NiL](-) anions form columns along the a axis by O-H?O hydrogen bonds. Additional hydrogen bonds between the uncoordinated and coordinated water molecules help to consolidate the crystal packing.

Project description:The ligand N-(2-hydr-oxy-3-methoxy-benzyl-idene)glycylglycine (H(3)L), a Schiff base derived from glycylglycine and 3-methoxy-salicylaldehyde, was used in the synthesis of a new organic-inorganic coordination complex, [Mn(H(2)O)(6)][Cu(C(12)H(11)N(2)O(5))](2)·6H(2)O. The Mn(II) atom is located on an inversion center and is coordinated to six water mol-ecules in a slightly distorted octa-hedral geometry. The Cu(II) atom is chelated by the tetra-dentate Schiff base ligand in a distorted CuN(2)O(2) square-planar coordination.

Additional hydrogen bonds of the same type further link the columns into a three-dimensional network.
