Özet

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-1-NMR, C-13-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 (C19H18N2O2Fe) crystallizes in the monoclinic space group P21/c and Z = 4, with a = 8.6970(4) , b = 18.4725(9) , c = 11.0041(5) , beta = 110.942(3)A degrees. Compound 4 (C19H18N2OSFe) crystallizes in the orthorhombic space group Fdd2 and Z = 16, with a = 84.242(2) , b = 13.5416(5) , c = 5.9405(2) , beta = 90A degrees. In terms of crystal packing, each compound shows different molecular arrangement, which are stabilized by C-H center dot center dot center dot O intermolecular weak hydrogen bonds, and/or C-H center dot center dot center dot pi interactions.
