X-ray structure determinations of mesitylene- and dimesitylmethane-derived compounds bearing bromomethyl units (compounds 1–3) show that the crystal packing of the molecules is characterized by the presence of C–H⋯Br interactions, such as BrCH2

This paper is devoted to IR spectroscopic studies in polarized light of hydrogen bond systems in 3-hydroxypyridine crystals. These investigations were preceded by re-determination of the 3-hydroxypyridine X-ray structure; in contrast to the previous

Eight compounds of the type (RSO2)2N-C(O)-NR'2 , where R = Me or 4-tolyl and R' = Me, Et, iPr or Ph, were obtained in good yields by treating the corresponding carbamoyl chlorides R'2NC(0)C1 with silver salts AgN (SO2R)2 in acetonitrile solution. The

We have redetermined the known structures of (i) methylthiourea (MTU) and (ii) 1,1-dimethylthiourea (1,1-DMTU), and investigated the structure of 1,3-dimethylthiourea (1,3-DMTU), which was however severely disordered. We report the structures of crys

Me3SnN(SO2Me)2 · 4,4′-bpy is obtained as an amorphous powder by treating a suspension of Me3SnN(SO2Me)2 in Et2O with one equivalent of 4,4′-bipyridine. It crystallizes from MeCN as a labile (1/1)-solvate. The crystallographic data of the latter
