The crystal and molecular structures of 1 -Methyl-2-1sopropyl-5-Nitroimidazole (A) and
1 -Methyl-2(Thiophenyl)-Methyl-5-Nitroimidazo(lBe ) derivatives were determined by X-ray diffraction
methods.
The compound A, C ~ H I ~0 2N. crystallises in the monoclinic space group P2 /c with
a = 9.9582(2) 8,. b = 6.5240(4) 1, c = 13.5560(3) 8,. p = 99.8930( 17)'. V = 867.6(5) A', 2 = 4,
Dcalc = 1.295 Mg/m3, p= 0.813 mm-', Fm = 360, CuKu = 1.5406 8, and R = 0.09. The five membered
ring with two nitrogen atoms is planar. Layering is observed down a and b axes.
The compound B, Cl lHl,N 3O2S. crystallises in the triclinic space group PI with a = 6.270(10)
8,. b = 27.874(12) A, C= 12.960(3) 8,. a = 90". p = 89.90". y= 90". V = 2266(35) A3, Z= 8.
DcaIc=1 .461 Mg/m3.p=2.504mm-l.Fm= 1040,CuKa = 1.54068,andR=0.11.
