Abstract
Reactions of
E -4-ferrocenylpent-3-en-2-one with
S -methyldithiocarbazate or
S -benzyldithiocarbazate result in the formation of methyl 5-ferrocenyl-3,5-dimethyl-2-pyrazoline-1-dithiocarboxylate (1) or benzyl 5-ferrocenyl-3,5-dimethyl-2-pyrazoline-1-dithiocarboxylate (2). The single crystals of both products are obtained and their structures are identified by X-ray diffraction method with triclinic
P -1 space groups. The cell parameters for compound 1 are as follows:
a = 7.7029(8) Å,
b = 10.1631(11) Å,
c = 10.7305(12) Å, α = 101.3270(10)°, β = 90.6740(10)°, γ = 94.8390(10)°, and
V = 820.40(15) Å
3. For compound 2, the crystallographic data are:
a = 7.953(3) Å,
b = 10.970(5) Å,
c = 12.534(3) Å, α = 84.718(5)°, β = 81.651(3)°, γ = 76.274(4)°, and
V = 1049.1(7) Å
