Crystal structure of N,N′-dibenzylpyromellitic diimide
The title compound, C24H16N2O4 [systematic name: 2,6-di-benzyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-one], consists of a central pyromellitic di-imide moiety with terminal benzyl groups at the N-atom positions. The mol-ecule is located about an inversion centre, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, both terminal phenyl groups, tilted by 72.97 (4)° with ...

The title compound, C(26)H(24)N(2)O(4), consists of a symmetrical mol-ecule that lies across a crystallographic inversion centre. The C-C distance in the triple bond is 1.188 (2) Å and there is also an inter-molecular C-H⋯O contact from a terminal acetyl-ene C-H to one of the dimiide O atoms [3.4349 (19) Å].
متن کاملN,N′-Di-8-quinolyladipamide
The complete molecule of the title compound, C(24)H(22)N(4)O(2), is generated by a crystallographic inversion centre located at the mid-point of the central C-C bond. The quinoline ring system and the hexyl chain are both essentially planar, and the dihedral angle between them is 46.30 (2)°. Intra-molecular N-H⋯N and C-H⋯O hydrogen bonds form five- and six-numbered rings, respectively. The crys...
متن کاملN,N′-Di-p-tolylethylenediamine
The asymmetric unit of the title compound, C(16)H(20)N(2), contains two independent mol-ecules. The rings in each mol-ecule are oriented at dihedral angles of 78.94 (3) and 77.76 (3)°.
متن کامل1,3-Di-n-butylthiourea
In the title compound, C(9)H(20)N(2)S, the n-butyl groups are in syn and anti positions in relation to the C=S bond. In the crystal, two mol-ecules are connected by two N-H⋯S=C hydrogen bonds into a centrosymmetric dimer. Another N-H⋯S=C hydrogen bond links the dimers, forming layers with a hydro-philic inter-ior and a hydro-phobic exterior, which spread across the (100) plane. Inter-lacing of ...
