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 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.

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.

In the structure of the title compound, C46H37N3O4S, the planes of the two isoindoline units make a dihedral angle of 77.86 (3)°. The dihedral angles between the benzyl plane and the isoindoline units are 79.56 (4) and 3.74 (9)°. The geometry at the S atom shows a short [1.7748 (17) Å] S-Cbenz-yl and a long [1.8820 (15) Å] S-Ctrit-yl bond and the C-S-C angle is 108.40 (7)°. N-C bond lengths aro...
متن کاملCrystal structure of bis(diphenylphosphino)ethane bis(2-selenopyridinato)platinum(II).
attracted considerable attention in recent years due to their diverse structural possibilities and relevance in materials science.1–3 Mononuclear cis complexes, [M(ER)2L2], are useful precursors for the synthesis of biand poly-nuclear complexes.2,3 These complexes are usually derived from simple organochalcogenolate ions. Internally functionalized organochalcogenolates, such as 2-selenopyridina...
