Hexaaqua-magnesium(II) bis-{[N-(4-meth-oxy-2-oxidobenzyl-idene)glycyl-glycinato(3-)]cuprate(II)} hexa-hydrate.

ABSTRACT: In the title complex, [Mg(H(2)O)(6)][Cu(C(12)H(11)N(2)O(5))](2)·6H(2)O, the Cu(II) atoms lie at the center of the square plane of triple negatively charged O,N,N',O'-tetra-dentate Schiff base ligands, which are coordinated by one phenolate O atom, one imine N atom, one deprotonated amide N atom and one carboxyl-ate O atom. The Mg(II) center, which sits on an inversion center, is coordinated by six aqua ligands and exhibits a slightly distorted octa-hedral conformation. The asymmetric unit consists of an [N-(4-meth-oxy-2-oxidobenzyl-idene)glycyl-glycinato]cuprate(II) anion, one half of an [Mg(H(2)O)(6)](2+) cation and three free water mol-ecules. The cations and anions form columns by O-H?O hydrogen bonds.

Hexaaqua-cadmium(II) bis-{[N-(2-oxidobenzyl-idene)glycyl-l-leucinato]cuprate(II)} dihydrate.

Project description:The title compound, [Cd(H(2)O)(6)][Cu(C(15)H(17)N(2)O(4))](2)·2H(2)O, has a chiral structure. Copper has a square-planar coordination with two N and two O atoms of the quadridentate chiral Schiff base ligand. The Cd(2+) ion is coordinated by six aqua ligands with a slightly distorted octa-hedral configuration. Ions are linked by O-H⋯O hydrogen bonds, and the [Cd(H(2)O)(6)](2+) cations and [CuL](-) anions (L = Schiff base derived from glycyl-l-leucine and salicylaldehyde) occupy a stacking structure within well separated columns along the a axis. The two crystallographically independent copper-Schiff base anions each have a chiral carbon centre with an S configuration. They are related by a non-crystallographic twofold rotation axis parallel to the [010] direction.

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 Cu(II) atom is chelated by the tetra-dentate Schiff base ligand in a distorted CuN(2)O(2) square-planar coordination. In the crystal structure, the complex [Mn(H(2)O)(6)](2+) cations and the [CuL](-) anions are arranged in columns parallel to the a axis and are held together by O-H⋯O hydrogen bonding. Additional hydrogen bonds of the same type further link the columns into a three-dimensional network.

Aqua-(4-methyl-quinoline-?N)[N-(2-oxidobenzyl-idene)glycinato-?O,N,O']copper(II) hemihydrate.

Project description:The title complex, [Cu(C(9)H(7)NO(3))(C(10)H(9)N)(H(2)O)]·0.5H(2)O, crystallizes with two independent formula units in the asymmetric unit; the solvent mol-ecule is located on a twofold axis of symmetry. The Cu(II) atom is coordinated by one tridentate N-salicylideneglycinate Schiff base ligand, one 4-methyl-quinoline ligand and one water mol-ecule, leading to a slightly distorted square-pyramidal N(2)O(3) geometry. In the crystal structure, the mol-ecules are linked by O-H?O hydrogen bonds into linear chains in the [100] direction. The structure is further stabilized by inter-molecular C-H?O inter-actions and C?C contacts with C?C = 3.3058?(2), 3.3636?(2) and 3.3946?(2)?Å.
