Neat 3,5-dinitro-1H-1,2,4-triazole was obtained in quantitative yield from potassium 3,5-dinitro-1,2,4-triazolate and sulfuric acid. The compound was purified by sublimation in vacuo at 110 °C. Pure HDNT is a hygroscopic white solid that is impact and friction sensitive and decomposes explosively upon heating to 170 °C. However, the presence of impurities might lower the decomposition temperatu...

In the title compound, C(11)H(8)ClN(3), the azo group adopts a trans conformation and the dihedral angle between the six-membered rings is 15.47 (8)°.

The title compound, C(6)H(5)Cl(2)N, is almost planar, with an r.m.s. deviation of 0.0146 Å for all atoms except for the 5-choloromethyl Cl atom. The offset Cl atom lies above this plane with a Cl-C-C angle of 111.11 (17)°. In the crystal, mol-ecules are connected via inter-molecular C-H⋯N hydrogen bonds, forming dimers.

The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))](n), comprises an Rb cation and a 3,5-dinitro-benzoate anion. The Rb cation is eight-coordinated by O atoms from five 3,5-dinitro-benzoate anions. On the other hand, each 3,5-dinitro-benzoate anion links five Rb cations with the carboxyl-ate groups as μ(3)-bridging. The metal atom is firstly linked by the carboxyl-ate groups into ...

The title compound, C(6)HCl(6)N, lies on a mirror plane, the asymmetric unit conataining a half-mol-ecule. Weak intra-molecular C-H⋯Cl contacts are observed.

In the title complex, [Sn(C(6)H(5))(3)(C(8)H(5)N(2)O(6))(CH(3)OH)], the Sn(IV) ion is coordinated in a slightly distorted trigonal-bipyramidal geometry by three phenyl ligands in the equatorial plane and by a 2-methyl-3,5-dinitro-benzene-carboxyl-ato ligand and a methanol ligand at the apical sites. In the crystal, complex mol-ecules are linked via inter-molecular O-H⋯O hydrogen bonds, forming ...

Various 4'-hydroxy-3',5'-dinitro substituted chalcones 1 and S-benzylthiouronium chloride (SBT) 2 in the presence of DMF-organic bases (morpholine/ pyrrolidine/ piperidine) gave 4,6-diaryl-2-(4-morpholinyl / 1pyrrolidinyl /1-piperidinyl)pyrimidines 4, 5 and 6 in a facile one-pot conversion. In an another attempt reactants 1 and 2 yielded intermediate 2-benzylthiopyrimidines 3, in presence of DM...

In the title gem-dinitro-azetidinium 2-hy-droxy-benzoate salt, C(3)H(6)N(3)O(4) (+)·C(7)H(5)O(3) (-), the azetidine ring is virtually planar, with a mean deviation from the plane of 0.0242 Å. The dihedral angle between the two nitro groups is 87.5 (1)°.

In the title coordination polymer, {[Ba(C(7)H(2)N(2)O(7))(H(2)O)(2)]·H(2)O}(n), the Ba(II) atom is ten-coordinated by seven O atoms from four 3,5-dinitro-salicylatate ligands, two μ(2)-bridging aqua ligands and one water mol-ecule. The coordination mode is best described as a bicapped square-anti-prismatic geometry. The 3,5-dinitrosalicylatate ligands bridge three Ba atoms. Centrosymmetrically ...
