Propane-1,3-diyl bis-(4-amino-benzoate).

ABSTRACT: Mol-ecules of the title compound, C(17)H(18)N(2)O(4), lie on a twofold rotation axis that passes through the central methyl-ene C atom. The mol-ecules adopt a 'V' shape and the trimethyl-ene unit assumes a gauche-gauche conformation. The amino N atom shows a nonplanar coordination. Adjacent mol-ecules are connected by N-H?O hydrogen bonds into chains running along [001]. Furthermore, N-H?N hydrogen bonds connect these chains into a three-dimensional network.

Propane-1,3-diyl bis-(pyridine-4-carboxyl-ate).

Project description:The title compound. C(15)H(14)N(2)O(4), (I), has a gauche-gauche (O/C/C/C-O/C/C/C or GG) conformation and is a positional isomer of propane-1,3-diyl bis-(pyridine-3-carboxyl-ate), (II). The mol-ecule of (I) lies on a twofold rotation axis, which passes through the central C atom of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. There is excellent agreement of the geometric parameters of (I) and (II). The most obvious differences between them are the O/C/C/C-O/C/C/C torsion angles [56.6?(2)° in (I) and 174.0?(3)/70.2?(3)° in (II) for GG and TG conformations, respectively] and the dihedral angle between the planes of the aromatic rings [80.3?(10)° in (I) and 76.5?(3)° in (II)]. The crystal structure is stabilized by weak C-H? N and C-H? O hydrogen bonding.

1,3-Bis(4-fluoro-phen-yl)-N,N'-(propane-1,3-diyl-idene)dihydroxyl-amine.

Project description:The title compound, C(15)H(12)F(2)N(2)O(2), crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both aromatic rings of both mol-ecules are disordered over two orientations [occupancy ratios of 0.768?(3):0.232?(3) and 0.770?(3):0.230?(3) for mol-ecule A and 0.789?(3):0.211?(3) and 0.789?(3):0.211?(3) for mol-ecule B]. The dihedral angles between the planes of the major and minor components of the disordered aromatic rings are 72.0?(4) and 71.2?(4)° for mol-ecule A, and 70.2?(4) and 71.5?(2)° for mol-ecule B. In the crystal, both mol-ecules form inversion dimers with R(2) (2)(6) ring motifs via pairs of inter-molecular O-H?N hydrogen bonds. The dimers are linked, forming zigzag C(7) chains along the c axis. Weak C-H?? inter-actions help to consolidate the packing.

1,3-Bis[(4-methylbenzylidene)amino-oxy]propane.

Project description:The title bis-oxime compound, C(19)H(22)N(2)O(2), synthesized by the reaction of 4-methyl-2-hydroxy-benzaldehyde with 1,3-bis-(amino-oxy)propane in ethanol, adopts a V-shaped conformation. The dihedral angle between the rings is 84.59?(3)°. The mol-ecule is disposed about a crystallographic twofold rotation axis, with one C atom lying on the axis. In the crystal, mol-ecules are packed by C-H??(Ph) inter-actions, forming chains.

A monoclinic modification of propane-1,3-diyl bis-(pyridine-3-carboxyl-ate).

Project description:In the title compound, C(15)H(14)N(2)O(4), (I), the mol-ecule lies on a twofold rotation axis which passes through the central C atom of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. The structure is a monoclinic polymorph of the triclinic structure previously reported [Brito, Vallejos, Bolte & López-Rodríguez (2010). Acta Cryst. E66, o792], (II). The most obvious difference between them is the O/C/C/C-O/C/C/C torsion angle [58.2 (7)° in (I) and 173.4 (3)/70.2 (3)° in (II) for GG and TG conformations, respectively]. Another important difference is observed in the dihedral angle between the planes of the aromatic rings [86.49 (7)° for (I) and 76.4 (3)° for (II)]. The crystal structure features a weak π-π inter-action [centroid-centroid distance = 4.1397 (10)Å]; this latter kind of inter-action is not evident in the triclinic polymorph.

catena-Poly[[[bis-[2,2'-(propane-1,3-diyl-dithio)bis-(1,3,4-thia-diazole)-?N]copper(II)]-bis-[?-2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole)-?N:N]] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C(7)H(8)N(4)S(4))(4)](ClO(4))(2)}(n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by six N atoms of three symmetry-related 2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole) (L) ligands in a slightly distorted octa-hedral geometry. The ligand L adopts two kinds of coordination modes in the crystal structure; one is a monodentate coordination mode and serves to complete the octa-hedral coordination of the Cu atom and the other is an N:N'-bidentate bridging mode in a trans configuration, bridging Cu atoms via translation symmetry along the b axis into a chain structure. The perchlorate ions serve as acceptors for inter-molecular C-H?O hydrogen bonds, which link the chains into a three-dimensional network.

In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules, forming an infinite three-dimensional supra-molecular structure.
