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

ABSTRACT: 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.

A nitrate and a half-occupancy water ligand form long coordination bonds to the Pb(II) ions capping the trigonal-prismatic environment. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network. C-H?O inter-actions also occur.

In addition, the O atom of the unique solvent water mol-ecule is disorded over two sites with equal occupancies.

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.

[N,N,N',N'-Tetra-kis(benzimidazol-2-ylmeth-yl)cyclo-hexane-1,2-trans-diamine]-iron(II) bis-(perchlorate) methanol solvate.

Project description:In the title compound, [Fe(C(38)H(38)N(10))](ClO(4))(2)·CH(3)OH, the Fe(II) atom has a distorted octa-hedral coordination environment with four benzimidazol N atoms and two amino N atoms from an N,N,N',N'-tetra-kis-(benzimidazol-2-ylmeth-yl)cyclo-hexane-1,2-trans-diamine ligand. The uncoordinated solvent methanol mol-ecule is hydrogen bonded to an O atom of a perchlorate anion. One of the perchlorate anions is disordered over two sets of sites with occupancy factors of 0.539?(14) and 0.461?(14). N-H?O and C-H?O hydrogen bonds, as well as ?-? stacking inter-actions between the imidazol rings and between the imidazol and benzene rings [centroid-centroid distances = 3.714?(2) and 3.705?(2)?Å] give rise to a three-dimensional network.

(1R,2R)-N,N'-Dimethyl-cyclo-hexane-1,2-diamine.

Project description:The molecule of the title compound, C(8)H(18)N(2), possesses C(2) symmetry. Owing to its stereochemistry, it is used in the synthesis of chiral ligands and metal complexes for asymmetric synthesis. The cyclo-hexane ring shows a chair conformation with the amino groups in equatorial positions. Contrary to the literature, the title compound is not a liquid, but a crystalline solid at room temperature (293 K). The absolute configuration is assigned from the synthesis.

Project description:In the title salt, [Zn(2)(C(2)H(8)N(2))(5)](ClO(4))(4), an ethyl-enediamine mol-ecule bridges two bis-(ethyl-enediamine)-zinc units; the five-coordinate Zn atoms show a trigonal-bipyramidal coordination geometry that is distorted towards square-pyramidal (that of one Zn atom is distorted by 12% and that of the other by 34%). The perchlorate ions are all disordered over two positions in a 1:1 ratio. The cation inter-acts weakly with the anion by N-H⋯O hydrogen bonds, generating a three-dimensional network.

Project description:In the structure of the title compound, [Fe(2)(C(5)H(5))(2)(C(18)H(24)N(2))], the cyclo-hexane ring has a chair configuration and the two ferrocenemethyl-amino groups are bonded to it equatorially, as expected. The configuration of the two ferrocence nuclei may be due to intra-molecular N-H?N hydrogen bonding involving the two NH groups.

(1R,2R)-N,N'-Diisobutyl-N,N'-dimethyl-cyclo-hexane-1,2-diamine.

Project description:The title compound, C(16)H(34)N(2), is a chiral diamine with fixed R configuration at both stereogenic carbon centres of the cyclo-hexane backbone. Due to their different substituents, the two N atoms also become stereogenic. In the crystal structure, the configuration at one of the two nitro-gen centres is fixed, with the free electron pair pointing inward and the isobutyl group in a trans position towards the cyclo-hexane backbone resulting in an R configuration. The isobutyl group at the second N atom, however, is disordered with 75% S configuration and 25% R configuration. In both cases, the isobutyl group is arranged in a trans position towards the cyclo-hexane backbone.
