The use of appropriate level of theories for studying weak van der Waal interactions such as 8-8stacking interactions of aromatic molecules has been an important aspect, since the high levelmethods have limitations for application to large molecules. The differences in the stacking energiesof various aromatic molecular structures are found significant. It is also very important for identifyingt...

The reaction of CoCl(2).6H(2)O with m-BDTH(2) (1,3-benzeneditetrazol-5-yl) leads to [Co(C(8)H(6)N(8))(2)(H(2)O)(2)(CH(3)CN)(2)]Cl(2) (1). Both tetrazolic groups remain protonated existing in a 1H tautomeric form. A trifurcated chlorine atom and stacking interactions assemble compound 1 into a three-dimensional network.

Four imidazo[2,1-b][1,3,4]thiadiazoles containing a simply-substituted 6-aryl group have been synthesized by reaction of 2-amino-1,3,4-thiadiazoles with bromoacetylarenes using microwave irradiation and brief reaction times. 6-(2-Chlorophenyl)imidazo[2,1-b][1,3,4]thiadiazole, C(10)H(6)ClN(3)S, (I), 6-(2-chlorophenyl)-2-methylimidazo[2,1-b][1,3,4]thiadiazole, C(11)H(8)ClN(3)S, (II), 6-(3,4-dichl...

Hydrolyses of HC[triple bond]CSO3SiMe3 (1) and CH3C[triple bond]CSO3SiMe3(2) lead to the formation of acetylenic sulfonic acids HC[triple bond]CSO3H.2.33H2O (3)and CH3C[triple bond]CSO3H.1.88H2O (4). These acids were reacted with guanidinium carbonate to yield [+C(NH2)3][HC[triple bond]CSO3] (5) and [+C(NH2)3][CH3C[triple bond]CSO3] (6). Compounds 1-6 were characterized by spectroscopic methods...
