%X New isonicotinohydrazone compounds, N¡¯-(3-bromobenzylidene)isonicotinohydrazide (1) and N¡¯-(2,3-difluorobenzylidene)isonicotinohydrazide (2), were prepared and structurally characterized by elemental analysis, IR, UV and 1H NMR spectra, and single crystal X-ray determination. Compound 1 crystallizes in the monoclinic space group P21/n with unit cell dimensions a = 7.600(2) £¿, b = 11.365(2) £¿, c = 14.412(2) £¿, ¦Â = 101.748(2)o, V = 1218.7(4) £¿3, Z = 4, R1 = 0.0335, and wR2 = 0.0745. Compound 2 crystallizes in the triclinic space group P-1 with unit cell dimensions a = 7.6241(6) £¿, b = 11.3937(9) £¿, c = 14.335(1) £¿, ¦Á = 79.664(1)o, ¦Â = 75.990(1)o, ¦Ã = 71.159(1)o, V = 1136.5(2) £¿3, Z = 4, R1 = 0.0345, and wR2 = 0.0940. Structures of both compounds are stabilized by hydrogen bonds and ¦Ð¡¤¡¤¡¤¦Ð interactions.
