Abstract

The presem paper describes the crysral and molecular structure of 5-bromo-2-(2-methylnitroethenyl)furan, (C1H6N03Br). The title compound crystallizes in triclinic system; space group PI; cell parameters: a =7 .428(2) Á, b = 10.762(3) Á, c = 1 0.932(4) Á, ex =84 .74(3)0, B =7 5.98(3)0, y = 81.73(3)°; R=O .065 5 for l 587 observed retlections wi1h I > 3cr(l), wR =O .084 2. The structure has been determined from X-ray diffraction data recorded at 293(1) K, and solved by direct methods. The s1ruc1ural parameters were refined by full-matrix least-squares analysis, to 218 refined parameters (H atoms riding). Some C-H .. -0 intermolecular and i.ntramolecular short contacts are noted with H .. ,Q distances < 2.7Á.T he molecules in the crystal are held together by weak intermolecular C-H .. ·O imeractions and va11 der Waals forces.
