Crystal structure of (±)-[trans-cyclo-hexane-1,2-diylbis(aza-nedi-yl)]di-phospho-nium dibromide dichloro-methane disolvate.

ABSTRACT: The cation of the title solvated salt, C42H42N2P2 (2+)·2Br(-)·2CH2Cl2, lies on a crystallographic twofold rotation axis. The 1,2-di-amino-cyclo-hexane fragment has a chair conformation with two N atoms in a transoid conformation [N-C-C-N = 163.4?(2)°]. In the crystal, the cations are linked to the anions by N-H?Br and C-H?Br hydrogen bonds, forming a chain structure along the c axis. The di-chloro-methane mol-ecule takes part in the hydrogen-bond network through C-H?? and C-H?Br inter-actions.

The cation of the title solvated salt, C42H42N2P2 (2+)·2Br(-)·2CH2Cl2, lies on a crystallographic twofold rotation axis. The 1,2-di-amino-cyclo-hexane fragment has a chair conformation with two N atoms in a transoid conformation [N-C-C-N = 163.4 (2)°]. In the crystal, the cations are linked to the anions by N-H⋯Br and C-H⋯Br hydrogen bonds, forming a chain structure along the c axis. The di-chloro-methane mol-ecule takes part in the hydrogen-bond network through C-H⋯π and C-H⋯Br inter-actions. ...[more]

Project description:The alkyl-ammonium chain of the dication in the title mitochondrially targeted (5-ammonio-pent-yl)triphenyl--phos-pho-nium dibromide ethanol solvate, C(23)H(28)NP(2+)·2Br(-)·C(2)H(6)O, is almost planar (r.m.s deviation = 0.0716?Å for all non-H atoms) and in the extended form, maximizing the P?N distance [7.716?(2)?Å].

(m-Phenyl-enedimethyl-ene)bis-(triphenyl-phospho-nium) bis-[chlorido(penta-fluoro-phen-yl)aurate(I)] dichloro-methane disolvate.

Project description:The title compound, (C(44)H(38)P(2))[AuCl(C(6)F(5))](2)·2CH(2)Cl(2), crystallizes with a twofold rotation axis through the central benzene ring in the bis-phospho-nium dication. In the crystal, the dications and anions are ordered into columns running parallel to the c axis by contacts of the pro-ylidic CH(2) groups with the Cl atom of one and an ortho-F atom of another anion. The space between the columns is occupied by CH(2)Cl(2) solvent mol-ecules.

(3Z,3'E)-3,3'-[Cyclo-hexane-1,2-diylbis(aza-nylyl-idene)]bis-(indolin-2-one) N,N-dimethyl-formamide monosolvate dihydrate.

Project description:In the Schiff base mol-ecule of the title compound, C(22)H(20)N(4)O(2)·C(3)H(7)NO·2H(2)O, the cyclo-hexane ring adopts a chair conformation with the two imine groups linked at the equatorial positions. The two indolin-2-one ring systems make a dihedral angle of 65.63 (5)°. In the crystal, the Schiff base mol-ecules are connected through bifurcated N-H⋯(O,N) hydrogen bonds, forming inversion dimers. The water molecules link the dimers and the dimethylformamide molecules via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds. Together with C-H⋯π and π-π [centroid-centroid distance = 3.3889 (10) Å] inter-actions a three-dimensional supra-molecular structure is formed.

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 π-π stacking inter-action are observed.

(2Z,2'Z)-Diethyl 3,3'-[butane-1,4-diylbis(aza-nedi-yl)]bis-(but-2-enoate).

Project description:The whole mol-ecule of the title ?-enamino-ester, C(16)H(28)N(2)O(4), is generated by a crystallographic inversion center, situated at the mid-point of the central C-C bond of the 1,4-diamino-butane segment. There are two intra-molecular N-H?O hydrogen bonds that generate S(6) ring motifs. This leads to the Z conformation about the C=C bonds [1.3756?(17)?Å]. The mol-ecule is S-shaped with the planar central 1,4-diamino-butane segment [maximum deviation for non H-atoms = 0.0058?(13)?Å] being inclined to the ethyl butyl-enonate fragment [C-C-O-C-C=C-C; maximum deviation = 0.0710?(12)?Å] by 15.56?(10)°. In the crystal, mol-ecules are linked via C-H?O inter-actions, leading to the formation of an undulating two-dimensional network lying parallel to the bc plane.

Dimethyl 3,3'-diphenyl-2,2'-[(S)-thio-phene-2,5-diylbis(carbonyl-aza-nedi-yl)]dipropano-ate.

Project description:The asymmetric unit of the title compound, C(26)H(26)N(2)O(6)S, contains two independent mol-ecules; each has twofold symmetry with the S atom and the mid-point of the C-C bond of the thio-phene ring located on a twofold rotation axis. In the two mol-ecules, the terminal benzene rings are oriented at dihedral angles of 65.8 (3) and 63.5 (3)° with respect to the central thio-phene rings. The meth-oxy-carbonyl group of one mol-ecule is disordered over two positions with site-occupancy factors of 0.277 (12) and 0.723 (12). Inter-molecular N-H⋯O hydrogen bonding is present in the crystal structure.

Bromido(1,4,7,10,13-penta-aza-cyclo-hexa-deca-ne)cobalt(III) dibromide dihydrate.

Project description:The title salt, [CoBr(C11H27N5)]Br2·2H2O, contains a complex cation with mirror symmetry and two Br(-) counter-anions that are likewise located on the mirror plane. The central Co(III) atom of the complex cation has one Br(-) ion in an axial position, one N atom of the penta-dentate macrocyclic ligand in the other axial position and four N atoms of the ligand in equatorial positions, defining a distorted octa-hedral coordination geometry. The macrocyclic ligand is coordinated to the Co(III) atom within a 5, 6, 5 arrangement of chelate rings in the equatorial plane of the four N atoms. Due to symmetry, the configuration of the chiral N atoms is 1RS, 4SR, 10RS, 13SR. In the crystal, N-H⋯Br, O-H⋯Br and N-H⋯O hydrogen bonds between the complex cation, anions and lattice water mol-ecules generate a three-dimensional network.

Project description:The title compound, C(56)H(56)Ge(4)O(2)·2CH(2)Cl(2) or Tol(8)Ge(4)O(2)·2CH(2)Cl(2) (Tol = p-CH(3)C(6)H(4)), was obtained serendipitously during the attempted synthesis of a branched oligogermane from Tol(3)GeNMe(2) and PhGeH(3).

The Ge-Ge bond distance is 2.4418 (5) Å and the Ge-O bond distances are 1.790 (2) and 1.785 (2) Å. The torsion angles within the Ge(4)O(2) ring are -56.7 (1) and 56.1 (1)° for the Ge-Ge-O-Ge angles and -43.9 (1)° for the O-Ge-Ge-O angle.
