Crystal structure of 1,2-bis[(2-tert-butylphenyl)imino]ethane
The whole molecule of the title compound, C22H28N2, (I), is generated by inversion symmetry. The mol-ecule is rather similar to that of 2,3-bis-[(2-tert-butyl-phen-yl)imino]-butane, (II), a di-imine ligand comprising similar structural features [Ferreira et al. (2006 ▶). Acta Cryst. E62, o4282-o4284]. Both ligands crystallize with the -N=C(R)-C(R)=N- group around an inversion centre, in a trans...
متن کاملCrystal structure of (1E,1′E)-N,N′-(ethane-1,2-diyl)bis[(pyridin-2-yl)methanimine]
The whole mol-ecule of the title compound, C14H14N4, is generated by twofold rotation symmetry. The twofold axis bis-ects the central -CH2-CH2- bond and the planes of the pyridine rings are inclined to one another by 65.60 (7)°. In the crystal, there are no significant inter-molecular inter-actions present.
متن کاملCrystal structure of 1-methoxy-2,2,2-tris(pyrazol-1-yl)ethane
The title compound, C12H14N6O, consists of three pyrazole rings bound via nitro-gen to the distal ethane carbon of meth-oxy ethane. The dihedral angles between the three pyrazole rings are 67.62 (14), 73.74 (14), and 78.92 (12)°. In the crystal, mol-ecules are linked by bifurcated C-H,H⋯N hydrogen bonds, forming double-stranded chains along [001]. The chains are linked via C-H⋯O hydrogen bonds,...
متن کاملCrystal structure of 2-methoxy-1-nitronaphthalene
The asymmetric unit of the title compound, C11H9NO3, contains two mol-ecules, A and B. In mol-ecule A, the dihedral angle between the planes of the naphthalene ring system (r.m.s. deviation = 0.003 Å) and the nitro group is 89.9 (2)°, and the C atom of the meth-oxy group deviates from the naphthyl plane by 0.022 (2) Å. Equivalent data for mol-ecule B are 0.008 Å, 65.9 (2)° and -0.198 (2) Å, res...
متن کاملCrystal structure of 4,4′-(ethane-1,2-diyl)bis(2,6-dibromoaniline)
In the title compound, C14H12Br4N2, the mol-ecule lies across an inversion center and hence the benzene rings are strictly coplanar. In the crystal, mol-ecules are linked by N-H⋯N and weak N-H⋯Br hydrogen bonds, forming a two-dimensional network parallel to (101). In addition, type II Br⋯Br inter-actions [3.625 (4) Å] complete a three-dimensional supra-molecular network.
