Dicyclo-hexyl-ammonium 3,5-dinitro-benzoate.

ABSTRACT: The asymmetric unit of the title salt, C(12)H(24)N(+)·C(7)H(3)N(2)O(6) (-), contains two cations and two anions. In the crystal, the cations and anions are connected by N-H⋯O hydrogen bonds, forming a 12-membered ring with an R(4) (4)(12) graph-set motif. The center of this 12-membered ring coincides with an inversion centre. π-π stacking is observed between parallel benzene rings [centroid-centriod distance = 3.771 (2) Å].

Dicyclo-hexyl-ammonium 2-methoxy-benzoate.

Project description:The asymmetric unit of the title compound, C(12)H(24)N(+)·C(8)H(7)O(3) (-), contains one dicyclo-hexyl-ammonium cation and one 2-methoxy-benzoate anion. Two cations and two anions are linked together to form a four-ion cluster through a set of N-H⋯O hydrogen bonds. Weak C-H⋯O hydrogen bonds connect the clusters into chains that are stacked along the crystallographic c axis.

N,N-Dicyclo-hexyl-3,5-dinitro-benzamide.

Project description:In the title compound, C(19)H(25)N(3)O(5), the benzene ring is not coplanar with the amide group [dihedral angle = 61.90?(5)°]. The cyclo-hexyl rings are in chair conformations. There is a strong inter-molecular inter-action between the C=O group of the amide group and the nitro group of an adjoining mol-ecule, with a short O?N distance of 2.7862?(17)?Å. In the crystal, C-H?O inter-actions occur along the [100] direction.

Isobutyl 3,5-dinitro-benzoate.

Project description:In the structure of the title compound, C(11)H(12)N(2)O(6), the mol-ecules are stacked along the b axis without any π-π inter-actions. The stacked columns are linked together by non-classical inter-molecular C-H⋯O inter-actions,. In the molecule, the nitro groups make dihedral angles of 9.4 (5) and 10.3 (5)° with the benzene ring.

Dicyclo-hexyl-ammonium thio-cyanate: monoclinic polymorph.

Project description:The title salt, C(12)H(24)N(+)·NCS(-), represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Khawar Rauf et al. (2008 ?). Acta Cryst. E64, o366]. Two independent formula units comprise the asymmetric unit with the major difference in their mol-ecular structures relating to the relative dispositions of the cyclo-hexyl rings [dihedral angles = 79.88?(6) and 67.72?(5)°]. Further, the independent anions form distinctive patterns of hydrogen-bonding inter-actions, i.e. 2 × N-H?N versus N-H?N and N-H?S. The resulting supra-molecular architecture is a supra-molecular chain along the c axis based on a square-wave topology.

Dicyclo-hexyl-ammonium hydrogen phenyl-phospho-nate.

Project description:In the title salt, [(C(6)H(11))(2)NH(2)](+)·[C(6)H(5)PO(2)(OH)](-), the anion is monodeprotonated and acts as both a hydrogen-bond donor and acceptor. The anions are linked by pairs of O-H⋯O inter-actions, forming inversion dimers with R(2) (2)(8) ring motifs. These dimers are bridged by two dicyclo-hexyl-aminium cations via pairs of N-H⋯O hydrogen bonds, giving R(4) (4)(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C-H⋯O inter-actions, forming a two-dimensional network lying parallel to (101).

Isopropyl 4-chloro-3,5-dinitro-benzoate.

Project description:In the title compound, C(10)H(9)ClN(2)O(6), the two nitro groups and the ester group are oriented with respect to the benzene ring at dihedral angles of 49.42?(13)/87.61?(13) and 9.10?(10)°, respectively. In the crystal structure, a weak C-H?O inter-action is present. A short Cl?O contact of 2.972?(2)?Å is also observed in the crystal structure.
