Different conformations and packing motifs in the crystal structures of four thio-phene-carbohydrazide-pyridine derivatives.

ABSTRACT: The crystal structures of four thio-phene-carbohydrazide-pyridine derivatives, viz. N'-[(E)-pyridin-3-yl-methyl-idene]thio-phene-2-carbohydrazide, C₁₁H₉N₃OS, (I), N'-[(E)-pyridin-2-yl-methyl-idene]thio-phene-2-carbohydrazide, C₁₁H₉N₃OS, (II), N-methyl-N'-[(E)-pyridin-2-yl-methyl-idene]thio-phene-2-carbohydrazide, C₁₂H₁₁N₃OS, (III) and N'-[(E)-pyridin-2-yl-methyl-idene]-2-(thio-phen-2-yl)ethano-hydrazide, C₁₂H₁₁N₃OS, (IV) are described. The dihedral angles between the thio-phene ring and the pyridine ring are 21.4 (2), 15.42 (14), 4.97 (8) and 83.52 (13)° for (I)-(IV), respectively. The thio-phene r
