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

ABSTRACT: 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.

[?-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.

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

Project description: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.

{?-N,N,N',N'-Tetra-kis[(diphenyl-phosphan-yl)meth-yl]benzene-1,4-diamine}-bis-[(2,2'-bipyrid-yl)copper(I)] bis-(tetra-fluoridoborate).

Project description:In the title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(58)H(52)N(2)P(4))](BF(4))(2), the dinuclear cation lies on an inversion centre. The Cu(I) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and two P atoms from an N,N,N',N'-tetra-kis-[(diphenyl-phos-phan-yl)meth-yl]benzene-1,4-diamine ligand in a distorted tetra-hedral geometry. In the crystal, inter-molecular C-H?F hydrogen bonds link the ions into layers parallel to [[Formula: see text]01]. ?-? inter-actions [centroid-centroid distance = 3.668?(4)?Å] are also observed. One F atom of the anion is disordered over two orientations with a refined occupancy ratio of 0.675?(13):0.325?(13).

[?-N,N,N',N'-Tetra-kis(diphenyl-phosphino-meth-yl)benzene-1,4-diamine-?P,P':P'',P''']bis-[bis-(nitrato-?O)palladium(II)].

Project description:The asymmetric unit of the title complex, [Pd(2)(NO(3))(4)(C(58)H(52)N(2)P(4))], contains one half-mol-ecule, in which the central benzene ring is located on a crystallographic centre of inversion. The Pd atom has a distorted square-planar coordination consisting of two P and two O atoms. In the crystal structure, inter-molecular C-H?O inter-actions link the mol-ecules into chains, and ?-? contacts between the phenyl rings [centroid-centroid distance = 3.928?(3)?Å] may further stabilize the structure.

Perchlorato[N,N,N',N'-tetra-kis(2-pyridyl-meth-yl)cyclo-hexane-1,2-diamine]manganese(II) perchlorate.

Project description:The asymmetric unit of the title compound, [Mn(ClO(4))(C(30)H(34)N(6))]ClO(4), consists of a cationic [Mn(ClO(4))(C(30)H(34)N(6))](+) complex and a perchlorate anion. In the complex, the Mn(2+) ion is seven-coordinated in an approximately penta-gonal-bipyramidal environment by six N atoms from the hexa-dentate N,N,N',N'-tetra-kis(2-pyridylmeth-yl)-cyclo-hexane-1,2-diamine (tpdach) ligand and one O atom from a perchlorate anion. The complex displays inter-molecular ?-? inter-actions between adjacent pyridine rings (centroid-to-centroid distance 4.133?Å). Moreover, there are weak intra- and inter-molecular C-H?O hydrogen bonds. The Cl atom and two O atoms of the perchlorate are disordered, with a site-occupancy factor of 0.59?(2) for the major component.

[?-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.

1,4-Dichloro-2,3-bis-(chloro-meth-yl)butane.

Project description:The title compound, C6H10Cl4, adopts a geometric arrangement with two C-Cl bonds anti-periplanar to C-H bonds and the other two anti-periplanar to C-C bonds. While minimising steric replusion, this arrangement still gives rise to some intramolecular C-H?Cl contacts. In the crystal, mol-ecules are connected into a three-dimensional architecture via further C-H?Cl contacts.

Poly[diaqua-(?(4)-benzene-1,2,4,5-tetra-carboxyl-ato)[?(2)-1,4-bis-(3-pyridyl-meth-yl)piperazine]dizinc(II)].

Project description:In the title compound, [Zn(2)(C(10)H(2)O(8))(C(16)H(20)N(4))(H(2)O)(2)](n), the Zn(II) atom is in a distorted tetra-hedral environment, being coordinated by one N atom from a 1,4-bis-(3-pyridyl-meth-yl)piperazine (3-bpmp) ligand, two O atoms from two carboxyl-ate groups of the pyromellitate anion and one water mol-ecule. The distortion of the tetrahedral coordination may be ascribed to the hydrogen bonds between the carboxyl-ate groups and the adjacent water mol-ecules. Each Zn(II) atom links to three organic ligands and each pyromellitate ligand coordinates to four Zn(II) atoms, forming a (3,4)-connected infinite three-dimensional framework. O-H?N inter-actions also occur.

Crystal structure of 1,4-bis-[5-(2-meth-oxy-phen-yl)-2H-tetra-zol-2-yl]butane.

Project description:The title compound, C20H22N8O2, was synthesized by the coupling reaction of a sodium tetra-zolate salt and di-bromo-butane in a molar ratio of 2:1. The reaction can produce several possible regioisomers and the title compound was separated as the major product. The X-ray crystallographic study confirmed that the title compound crystallizes in the monoclinic P21/c space group and possesses a bridging butyl-ene group that connects two identical phenyl tetra-zole moieties. The butyl-ene group is attached not to the first but the second nitro-gen atoms of both tetra-zole rings. The dihedral angles between the phenyl groups and the adjacent tetra-zolyl rings are 5.32?(6) and 15.37?(7)°. In the crystal, the mol-ecules form centrosymmetric dimers through C-H?O hydrogen bonds between a C-H group of the butyl-ene linker and the O atom of a meth-oxy group.
