1,1'-{[1,4-Phenyl-enebis(methyl-ene)]bis-(-oxy)bis-(3,1-phenyl-ene)}diethanone.

ABSTRACT: In the title compound, C(24)H(22)O(4), the centroid of the central benzene ring lies on a special position of 2/m site symmetry, while the terminal aromatic rings are located on a mirror plane. The central and terminal benzene rings are perpendic-ular to each other. In the crystal, the mol-ecules are connected via C-H?O hydrogen bonds into a three-dimensional polymeric structure. The network is further consolidated by a C-H?? inter-action.

In the title compound, C(24)H(22)O(4), the centroid of the central benzene ring lies on a special position of 2/m site symmetry, while the terminal aromatic rings are located on a mirror plane. The central and terminal benzene rings are perpendic-ular to each other. In the crystal, the mol-ecules are connected via C-H⋯O hydrogen bonds into a three-dimensional polymeric structure. The network is further consolidated by a C-H⋯π inter-action. ...[more]

Crystal structures and Hirshfeld surface analyses of 4,4'-{[1,3-phenyl-enebis(methyl-ene)]bis-(-oxy)}bis-(3-meth-oxy-benzaldehyde) and 4,4'-{[(1,4-phenyl-ene-bis(methyl-ene)]bis-(-oxy)}bis-(3-meth-oxy-benzalde-hyde).

Project description:The title compounds, C24H22O6 (I) and C24H22O6 (II), each crystallize with half a mol-ecule in the asymmetric unit. The whole mol-ecule of compound (I) is generated by twofold rotation symmetry, the twofold axis bis-ecting the central benzene ring. The whole mol-ecule of compound (II) is generated by inversion symmetry, the central benzene ring being located on an inversion center. In (I), the outer benzene rings are inclined to each other by 59.96 (10)° and by 36.74 (9)° to the central benzene ring. The corresponding dihedral angles in (II) are 0.0 and 89.87 (12)°. In the crystal of (I), mol-ecules are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming ribbons propagating along the [10] direction. In the crystal of (II), mol-ecules are linked by C-H⋯O hydrogen bonds, forming a supra-molecular framework. The Hirshfeld surface analyses indicate that for both compounds the H⋯H contacts are the most significant, followed by O⋯H/H⋯O and C⋯H/H⋯C contacts.

1,4-Phenyl-enebis(methyl-ene) dicarbamate.

Project description:The title compound, C(10)H(12)N(2)O(4), is a phenyl dicarbamate with crystallographically imposed inversion symmetry. The dihedral angle between the carbamo-yloxy plane [i.e. the plane of the N-C(O)-O fragment; r.m.s. deviation = 0.002?(3)?Å] and the plane of the aryl ring is 29.2?(1)°. In the crystal, two different centrosymmetric N-H?O hydrogen-bond inter-actions are observed; these are described as R(2) (2)(8) and R(2) (4)(8) in graph-set notation. The rings form an alternating sequence, linking the mol-ecules into a sheet structure parallel to (011).

[1,4-Phenyl-enebis(methyl-ene)]bis-(tri-phenyl-phospho-nium) bis-(tetra-fluoro-borate).

Project description:The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.329?(6) to 1.391?(6)?Å] deviate significantly from their standard values.

3,3'-Bis(quinolin-8-yl)-1,1'-[4,4'-methyl-enebis(4,1-phenyl-ene)]diurea.

Project description:The title compound, C(33)H(26)N(6)O(2), contains two 3-(quinolin-8-yl)urea groups linked to a diphenyl-methane. The asymmetric unit contains two mol-ecules, A and B.

The two benzene rings are twisted, making dihedral angles of 81.36?(8)° in A and 87.20?(9)° in B. The molecular structures are stabilized by intramolecular N-H?N hydrogen bonds. In the crystal, each urea O atom is involved in two N-H?O hydrogen bonds, generating two inter-penetrating three-dimensional sets of mol-ecules.

Project description:In the title solvate, C22H18O6·2C3H7NO, the complete dicarboxylic acid molecule is generated by a crystallographic twofold axis, which bisects the central benzene ring and one N,N-di-methyl-formamide solvent mol-ecule.

In the crystal, the acid molecules are linked to the solvent molecules via O-H?O and weak C-H?O hydrogen bonds. Further weak C-H?O inter-actions link adjacent acid mol-ecules into a three-dimensional network.

Project description:In the cation of the title mol-ecular salt, C(20)H(24)N(4) (2+)·2PF(6) (-), the central benzene ring makes dihedral angles of 84.19?(7) and 79.10?(7)° with the pendant imidazole rings.

In the crystal, the cations and anions are linked by numerous C-H?F hydrogen bonds, thereby forming a three-dimensional network.
