West Jesús Valdés Martínez Multidisciplinaria (Ciencias Naturales y Exactas) X Ray thioureas Hydrogen bonds The crystal and molecular structure of N-2-pyridylethyl-N-3- tolylthiourea, 1, was determined. 1 crystallizes as triclinic, P-1,a = 9.024(2) Å, b = 9.718(3) Å, c = 9.765(4) Å, α = 102.26(3)°, β =114.18(3)°, γ = 103.12(2)°, V = 714.4(4) Å3, Z = 2. Both thiourea NHgroups form intermolecular hydrogen bonds, NH with the thionesulfur atom and the NH with the pyridine nitrogen. When comparedwith other N-2-pyridylethyl-N-arylthioureas it is observed that thecentro-symmetric NH⋅⋅⋅S hydrogen bond is always present and theNH⋅⋅⋅N always H-bonds to the pyridine N atom but in some cases asan intra-molecular H-bond and in the other as an intermolecular Hbond.This difference may be due to variables introduced by the flexibilityof the molecules, whose effects on the crystal packing can notbe predicted. 2004 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47548405 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.4 Vol.48 |
