A series of 3-diferrocenyl dihydropyrazole derivatives were synthesized from acetylferrocene. The structures of these compounds were characterized by IR, ~1H NMR and MS. The crystal structure of compound 2b was determined via X-ray single-crystal diffraction. Compound 2b belongs to the triclinic system with space group P1, and the unit cell parameters are a=0.9275(4) nm, b=1.1327(5) nm, c=1.1912(5) nm, α=88.67(2)°, β=79.925(18)°, γ=70.345(18)°, V=1.1595(9) nm~3, Z=2, F(000)=560, D_c=1.553 g/ cm~3, μ=1.279 mm~(-1), R_1=0.0351, wR_2=0.0934.
