The CORSIKA 8 project is an international collaboration of scientists working together to deliver the most modern, flexible, robust and efficient framework for simulation ultra-high energy secondary particle cascades in matter. main application cosmic ray air shower simulations, but it can also be applied other problems astro(particle)-physics, physics nuclear physics. Besides a comprehensive s...

In the title compound, C(8)H(8)N(4), the dihedral angle between the triazole ring [maximum deviation = 0.003 (1) Å] and the benzene ring is 34.57 (7)°. In the crystal, mol-ecules are linked into sheets lying parallel to the ac plane via inter-molecular N-H⋯N and C-H⋯N hydrogen bonds. Aromatic π-π [centroid-centroid distance = 3.6750 (8) Å] stacking and N-H⋯π inter-actions are also observed.

The title compound, C(10)H(8)BrN, was obtained by slow addition of sodium azide to 8-bromo-1-naphthoic acid, followed by addition of aqueous ammonia. The crude product was crystallized from petroleum ether to give pink crystals. Compared to other 1,8-disubstituted naphthalene compounds, this compound exhibits less strain between the 1 and 8 substituents. Additionally, the NH protons form both i...

In the title compound, C(24)H(18)O(3), the dihedral angles between the mean planes of the five-membered furan ring and the meth-oxy-substituted benzene and the adjacent and outer biphenyl benzene rings are 2.43 (7), 4.48 (7) and 30.47 (8)°, respectively. The crystal packing is stabilized by weak C-H⋯O and C-H⋯π inter-molecular hydrogen bonds and π-π stacking inter-actions [centroid-centroid dis...

In the title compound, C(11)H(9)ClN(4)O(2), the dihedral angle between the aromatic rings is 79.67 (8)°. π-π stacking between centrosymmetrically related pairs of pyrimidine rings occurs along [100] [centroid-centroid separations = 3.4572 (8) and 3.5433 (7) Å].

In the title compound, C(14)H(8)ClN(3)S, the dihedral angle between the approximately planar triple-fused ring system (r.m.s. deviation = 0.065 Å) and the pendant phenyl ring is 62.25 (5)°. In the crystal, mol-ecules are linked into infinite chains along the c-axis direction by C-H⋯N hydrogen bonds. Aromatic π-π stacking inter-actions [centroid-centroid distances = 3.7499 (8) and 3.5644 (8) Å] ...
