1-Acetyl-3-ferrocenyl-5-methyl-1H-pyrazole and 1-acetyl-5-ferrocenyl-3-(2-pyridyl)-1H-pyrazole

Abstract: Molecules of 1-acetyl-3-ferrocenyl-5-methyl-1H-pyrazole, [Fe(C₅H₅)(C₁₁H₁₁N₂O)], form a centrosymmetric dimer generated by a combination of one C-H [pi] (pyrazole) and one C-H [pi] (cyclopentadienyl) interaction. The dimers are linked by C-H [pi] interactions, involving the pyrazole rings as acceptors, into layers parallel to (10 $\overline{1}$ ). Molecules of 1-acetyl-5-ferrocenyl-3-(2-pyridyl)-1H-pyrazole, [Fe(C₅H₅)(C₁₅H₁₂N₃O)], are linked by C-HO interactions into a chain running in the [010] direction. Two chains of this type passing through each unit cell are connected by O [pi] (pyridyl) interactions into an [010] double chain.

Formula: [Fe(C₅H₅)(C₁₁H₁₁N₂O)] and [Fe(C₅H₅)(C₁₅H₁₂N₃O)]
