Two novel ferrocenyl substituted N-acetyl-2-pyrazolines, N-acetyl-3-(2-furyl)-5-ferrocenyl-2-pyrazoline ( 3) and N-acetyl-3-(2-thienyl)-5-ferrocenyl-2-pyrazoline ( 4), have been synthesized and characterized by FTIR, H-NMR, C-NMR techniques, elemental analysis and X-ray structure analysis. Thermal properties of these compounds have been determined by TGA, DTA and DSC analysis. Compound 3 (CHNOFe) crystallizes in the monoclinic space group P21/ c and Z = 4, with a = 8.6970(4) Å, b = 18.4725(9) Å, c = 11.0041(5) Å, β = 110.942(3)°. Compound 4 (CHNOSFe) crystallizes in the orthorhombic space group Fdd2 and Z = 16, with a = 84.242(2) Å, b = 13.5416(5) Å, c = 5.9405(2) Å, β = 90°. In terms of crystal packing, each compound shows different molecular arrangement, which are stabilized by C-H···O intermolecular weak hydrogen bonds, and/or C-H···π interactions. Index Abstract: Two novel ferrocenyl-containing 2-pyrazolines have been synthesized and fully characterized by FT-IR, H-NMR, C-NMR techniques, elemental analysis and X-ray crystal structure analysis. Thermal properties of these compounds have been determined by TGA, DTA and DSC analysis.[Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR] |
