4-Hydrazino-1-methylpyrazolo[3,4-d]pyrimidine
The title compound, C(6)H(8)N(6), crystallizes as an N-H⋯N hydrogen-bond-linked dimer of two almost identical mol-ecules in the asymmetric unit. Both of the mol-ecules are almost planar (rms deviations of 0.0186 and 0.0296 Å in the two molecules) and their hydrazino groups are turned towards the pyrazole rings. The dimers are arranged into chains via inter-molecular N-H⋯N hydrogen bonds between...
متن کامل4-Hydrazino-2-(methylsulfanyl)pyrimidine
In the crystal of the title compound, C(5)H(8)N(4), centrosymmetric dimers are linked by pairs of N-H⋯N hydrogen bonds. Further N-H⋯N links result in a two-dimensional array whereby wave-like supra-molecular chains are inter-connected by R(2) (2)(8) ring motifs.

In the title compound, C(15)H(15)N(5)O(4)S, the dihedral angle between the pyrimidine and benzene rings is 84.56 (2)°. Intra-molecular hydrazine-carbonyl N-H⋯O and inter-molecular sulfonamide-pyridimine N-H⋯N hydrogen bonds stabilize the mol-ecular and crystal structures, respectively.
متن کاملBis{4-[(Z)-N′-(4-hydroxybenzylidene)hydrazino]-8-(trifluoromethyl)quinolinium} sulfate dihydrate
The title compound, 2C(17)H(13)F(3)N(3)O(+)·SO(4) (2-)·2H(2)O, crystallizes with four independent cations (A, B, C and D) in the asymmetric unit, which is composed of two groups of two cations, one anion and two water mol-ecules (Z' = 2). The dihedral angle between the mean planes of the 4-hydroxy-phenyl and quinolinium groups is 8.9 (7)° in A, 30.1 (6)° in B, 28.8 (8)° in C and 12.8 (1)° in D....
متن کاملN 2,N 2,N 4,N 4-Tetraethyl-6-{2-[(E)-1-(4-nitrophenyl)ethylidene]hydrazino}-1,3,5-triazine-2,4-diamine
The title compound, C(19)H(28)N(8)O(2), was prepared by the reaction of N(2),N(2),N(4),N(4)-tetra-ethyl-6-hydrazino-1,3,5-triazine-2,4-diamine and 1-(4-nitro-phen-yl)ethanone in ethanol at room temperature. The mol-ecular conformation is stabilized by intra-molecular C-H⋯N hydrogen-bonding inter-actions. There are also inter-molecular N-H⋯O hydrogen bonds, and C-H⋯π and π-π inter-actions, which...
