[?-N,N,N',N'-Tetra-kis(2-pyridyl-meth-yl)butane-1,4-diamine]-bis-[diacetato-cadmium(II)] nona-hydrate.

ABSTRACT: The title dinuclear complex, [Cd(2)(CH(3)CO(2))(4)(C(28)H(32)N(6))]·9H(2)O, is located on a crystallographic inversion center. The unique Cd(II) ion displays a 5 + 2 coordination. A distorted square-pyramidal geometry is formed by the dipicolyl-amine unit of the ligand via the N atoms in a meridional fashion and two O atoms of the acetate ligands with short Cd-O distances. The coordination is completed by two loosely bound O atoms of the acetate ligands. The Cd-N distances involving the pyridine N atoms differ slightly from each other and the Cd-N distance involving the tertiary N atom is the longest. In the crystal structure, complex mol-ecules and solvent water mol-ecules are connected into a three-dimensional network via inter-molecular O-H?O hydrogen bonds. One of the water mol-ecules lies on a twofold rotation axis.

[μ-N,N,N',N'-Tetra-kis(2-pyridyl-meth-yl)butane-1,4-diamine]-bis-[dibromidocopper(II)].

Project description:The title dinuclear copper complex, [Cu(2)Br(4)(C(28)H(32)N(6))], is located on an inversion center. The unique Cu(II) ion is in a slightly distorted square-pyramidal environment in which the N atoms of a dipicolyl-amine group and a bromide ligand form the basal plane. The apical site is occupied by a second Br atom. While the Cu-N distances involving the pyridine N atoms are the same within experimental error, the Cu-N distance involving the tertiary N atom is slightly elongated. Due to the typical Jahn-Teller distortion of copper(II) complexes, the apical Cu-Br distance is elongated.

[μ-N,N,N',N'-Tetra-kis(2-pyridyl-meth-yl)butane-1,4-diamine]-bis-[dichlorido-copper(II)] trihydrate.

Project description:The title dinuclear copper complex, [Cu(2)Cl(4)(C(28)H(32)N(6))]·3H(2)O, is located on a crystallographic inversion center. The unique Cu(II) ion is coordinated in a slightly distorted square-pyramidal environment in which the N atoms of the dipicolyl-amine group and a chloride ligand form the basal plane. The apical position is occupied by a second chloride atom. While the Cu-N distances of the pyridine N atoms are the same within expermental error, the Cu-N distance to the tertiary N atom is slightly elongated. The apical Cu-Cl distance is elongated due to typical Jahn-Teller distortion. One of the water O atoms was refined as disordered over two sites with occupancies 0.734 (17):0.266 (17) and another with half occupancy. H atoms for the disordered solvent atoms were not included in the refinement.

Poly[[[diaqua-cobalt(II)]-bis-[μ-1,1'-(butane-1,4-di-yl)diimidazole-κN:N]] dichloride tetra-hydrate].

Project description:In the title compound, {[Co(C(10)H(14)N(4))(2)(H(2)O)(2)]Cl(2)·4H(2)O}(n), the Co(II) atom and the mid-point of the 1,1'-butane-1,4-diyl-diimidazole ligands lie on inversion centers. The Co(II) atom is six-coordinated in a slightly distorted octa-hedral environment by four N atoms from four different ligands and by two O atoms from the water mol-ecules. The Co(II) atoms are bridged by the ligands into a (4,4) net. Adjacent nets are linked to the chloride anions and uncoordinated water mol-ecules via O-H⋯Cl and O-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular structure.

[μ-N,N,N',N'-Tetra-kis-(2-pyridyl-meth-yl)pentane-1,5-diamine]-bis-[dichlorido-copper(II)] sesquihydrate.

Project description:In the title dinuclear copper complex, [Cu(2)Cl(4)(C(29)H(34)N(6))]·1.5H(2)O, both Cu(II) ions are coordinated in a slightly distorted square-pyramidal environment in which the N atoms of the dipicolyl-amine group and a chloride ligand form the basal plane. The apical position is occupied by a second chloride atom. The Cu-N distances involving the pyridine N atoms differ slightly from each other and the Cu-N distance involving the tertiary N atom is the longest. The apical Cu-Cl distance is elongated compared to its basal counterpart due to typical Jahn-Teller distortion. In the crystal structure, complex and water mol-ecules are linked via inter-molecular O-H⋯O and O-H⋯Cl hydrogen bonds into chains along [001]. One of the water mol-ecules was refined with half occupancy.

N,N'-Bis(3,4-dimethoxy-benzyl-idene)butane-1,4-diamine.

Project description:The title Schiff base compound, C(22)H(28)N(2)O(4), was synthesized by the reaction of 3,4-dimethoxy-benzaldehyde and 1,4-diamino-butane in methanol. The mol-ecule is located on a center of inversion with one half-mol-ecule in the asymmetric unit. Both C=N double bonds are in a trans configuration. Inter-molecular C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

N,N'-Bis(4-bromo-benzyl-idene)butane-1,4-diamine.

Project description:The mol-ecule of the title Schiff base compound, C(18)H(18)Br(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the C=N bond. In the crystal structure, mol-ecules are linked into chains along [201] through inter-molecular Br?Br inter-actions [3.3747?(3)?Å], which are significantly shorter than the sum of the van der Waals radii for Br atoms (3.70?Å). The crystal structure is further stabilized by ?-? stacking inter-actions [centroid-centroid distance 3.6811?(11)?Å].

6-Methyl-1,3,5-triazine-2,4-diamine butane-1,4-diol monosolvate.

Project description:The title co-crystal, C4H7N5·C4H10O2, crystallizes with one mol-ecule of 6-methyl-1,3,5-triazine-2,4-diamine (DMT) and one mol-ecule of butane-1,4-diol in the asymmetric unit. The DMT mol-ecules form ribbons involving centrosymmetric R2(2)(8) dimer motifs between DMT mol-ecules along the c-axis direction. These ribbons are further hydrogen bonded to each other through butane-1,4-diol, forming sheets parallel to (121).

catena-Poly[[[diaqua-cadmium]-?-2,2'-(1,2-phenyl-enedi-oxy)diacetato] mono-hydrate].

Project description:In the title coordination complex, {[Cd(C(10)H(8)O(6))(H(2)O)(2)]·H(2)O}(n) the Cd(II) atom is seven-coordinated in a distorted penta-gonal-bipyramidal geometry, the penta-gonal plane comprising four O-atom donors from the 2,2'-(1,2-phenyl-enedi-oxy)diacetate chelate ligand together with a bridging carboxyl-ate O-atom donor, with the axial sites occupied by two water mol-ecules. The resulting helical chains extend along the b axis and are inter-connected by extensive O-H?O hydrogen-bonding inter-actions, which also involve the water mol-ecule of solvation, giving a three-dimensional structure.

Project description:The cation of the salt, [Mn(2)(C(14)H(14)N(4))(3)(H(2)O)(2)](ClO(4))(4), lies on a center of inversion, the center lying midway along the ethyl-ene chain of the bridging N,N'-bis-(2-pyridylmethyl-ene)ethane-1,2-diamine ligand. The Mn atom is chelated by two atoms N atoms of this bridging ligand, and is also coordinated by four N atoms of another ligand. The Mn atom is seven-coordinated in a penta-gonal-bipyramidal environment. The crystal structure displays inter-molecular π-π inter-actions between adjacent pyridine rings, with a shortest centroid-centroid distance of 3.784 (3) Å. The perchlorate is linked to the dinuclear cation by O-H⋯O hydrogen bonds.
