Dichlorido[(R,R)-N,N,N-tribenzyl-cyclo-hexane-1,2-diamine-?N,N]copper(II).

ABSTRACT: In the title compound, [CuCl(2)(C(27)H(32)N(2))], which bears a chiral diamine ligand, viz (R,R)-N,N,N''- tribenzyl-cyclo-hexane-1,2-diamine, the Cu(II) ion is ligated by two N and two Cl atoms in a distorted square-planar geometry. The coordination of the ligands to the Cu(II) ion results in the formation of a five-membered heterocyclic ring and a chiral center at the monosubstituted nitro-gen in an (S)-configuration. The catalytic capacity of the complex for the asymmetric nitro-aldol reaction is promising (49% ee).

Dichlorido[(1R,2R)-N-(pyridin-2-yl-methyl)cyclo-hexane-1,2-diamine-?N,N',N'']mercury(II).

Project description:In the title compound, [HgCl(2)(C(12)H(19)N(3))], the Hg(II) ion is coordinated by three N atoms of the (1R,2R)-N-(pyridin-2-ylmeth-yl)cyclo-hexane-1,2-diamine ligand and by a Cl atom in the basal plane, and by a second Cl atom in the apical position, within a distorted square-pyramidal geometry. The coordination of the enanti-opure ligand to the metal atom renders the central N atom chiral with an S configuration, so the complex is enanti-omerically pure and corresponds to the S,R,R diastereoisomer. Mol-ecules are linked via weak N-H?Cl hydrogen bonds into a one-dimensional hydrogen-bonding supramolecular chain along the crystallographic b axis.

trans-Diaqua-bis-(cyclo-hexane-1,2-diamine)-zinc(II) dichloride.

Project description:In the title compound, [Zn(C(6)H(14)N(2))(2)(H(2)O)(2)]Cl(2), the Zn(II) atom resides on a special position with site symmetry 2/m and is octa-hedrally coordinated by four N atoms from two trans 1,2-diamino-cyclo-hexane ligands and two water O atoms. In the crystal, N-H⋯Cl and O-H⋯Cl hydrogen bonds link the mol-ecules into a two-dimensional network parallel to the bc plane.

{2,2'-[Cyclo-hexane-1,2-diylbis(nitrilo-methanyl-ylidene)]diphenolato}copper(II).

Project description:The title compound, [Cu(C(20)H(20)N(2)O(2))], crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, the Cu(II) atom occupies the tetra-dentate N(2)O(2) cavity of the salen-type Schiff base ligand, adopting a distorted square-planar geometry with r.m.s. deviations of the coordin-ating atoms of 0.0522?(2) and 0.1128?(4)?Å. No hydrogen bonds or ?-? stacking inter-action are observed.

(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.

cis-[1,4-Bis(diphenyl-phosphan-yl)butane-?(2)P,P']dichlorido(cyclo-hexane-1,2-diamine-?(2)N,N')ruthenium(II) dichloro-methane monosolvate.

Project description:In the title compound, [RuCl(2)(C(6)H(14)N(2))(C(28)H(28)P(2))]·CH(2)Cl(2), the Ru(II) ion is coordinated in a slightly distorted octa-hedral environment, formed by two cis-oriented chloride ligands, two cis P atoms of a 1,4-bis-(diphenyl-phosphan-yl)butane ligand and two cis-chelating N atoms of a bidentate cyclo-hexane-1,2-diamine ligand. In the crystal, pairs of mol-ecules form inversion dimers via N-H?Cl hydrogen bonds. In addition, intra-molecular N-H?Cl and weak C-H?Cl, C-H?N, N-H?? and C-H?? hydrogen bonds are observed. One of the Cl atoms of the solvent mol-ecule is disordered over two sites with refined occupancies of 0.62?(1) and 0.38?(1).

(R,R)-N,N'-Bis(ferrocenylmeth-yl)cyclo-hexane-1,2-diamine.

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.

Project description:In the title compound, [Cu(C22H24N2O4)]·H2O, the Cu(II) atom is four-coordinated in a distorted planar geometry with a mean deviation of 0.1164?(2)?Å for the plane generated by the ligating atoms of the salen-type Schiff base ligand. In the crystal, O(water)-H?O and C-H?O hydrogen bonds form a three-dimensional-network.

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.
