Synthesis, Crystal Structure and Fluorescent Property. of a New Sulfanilamide Schiff-base Compound

A new sulfanilamide Schiff-base compound N,N'-(p-phenyl sulfanilamide)-5,6-dimethoxy- pyrimidine-(2-hydroxyl benzene) methylidene has been synthesized by the condensation of equimolar salicylaldehyde and 4-(p-amino phenyl sulfanilamide)-5,6-dimedioxy-pyrimidine in an anhydrous ethanol solution. The compound was characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P2(1)/c with a = 19.0425(11), b = 11.1914(6), c = 9.0075(5) angstrom, beta = 93.9650(10)degrees, Z = 4, V= 1915.01(18) angstrom(3), D(c) = 1.437 g/cm(3), M(r) = 414.43, lambda(MoK alpha) = 0.71073 angstrom, mu = 2.09 mm(-1), F(000) = 864, R = 0.0385 and wR = 0.1224.
