Redetermination of Crystal Structure of N,N'-bis (2-Hydroxybenzylidene)-2,2-Dimethyl-1,3-Propanediamine
The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...

In the title compound, the hydrated tetra-(nitrate) salt of dapsone (4,4'-di-amino-diphenyl-sulfone), 2C12H14N2O2S2+·4NO3-·H2O {alternative name: bis[bis-(4,4'-di-aza-niumylphen-yl) sulfone] tetra-nitrate monohydrate}, the cations are conformationally similar, with comparable dihedral angles between the two benzene rings in each of 70.03 (18) and 69.69 (19)°. In the crystal, mixed cation-anion-...
متن کامل1,4-Bis(2-diazoacetyl)piperazine
The asymmetric unit of the title compound, C8H10N6O2, contains one-half mol-ecule, which is completed by a crystallographic center of symmetry. The piperazine ring adopts a chair conformation. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into layers parallel to the bc plane. The crystal packing also exhibits short N⋯N contacts of 3.0467 (16) Å between the terminal diazo N atoms ...

The title compound, C(23)H(25)N(3)O(2), was obtained as an inter-mediary in the preparation of non-symmetric tertiary diamines. The mol-ecular structure presents T-shaped spatial form, in which the pyrimidine ring exhibits a chair conformation. The pyridyl ring is almost perpendicular to the phenyl rings with dihedral angles of 80.17 (8) and 76.03 (2)°. The phenol and amine groups are involved ...
