Four new crystal structures of sulfur and selenium analogues of 2[1H]-pyrimidinone derivatives were determined with the use of X-ray diffraction method. The molecular geometry and intermolecular interactions of the investigated molecules were analyzed in order to find the structural features and geometrical parameters, which can be responsible for antimicrobial activities. The influence of chalcogen...
In order to investigate how halogen substituents influence the crystal packing of 2-halogenpyridines, the crystal structure of 2-chloropyridine was determined and the crystal packing motives of 2-fluoropyridine and 2-chloropyridine were analyzed based on ab initio quantum-chemical calculations of the intermolecular interaction energy, using the MP2/6-311G(d,p) method. Graphical Abstract The limits...
