Abstract:The title compound, 2,4-dihydroxyacetopheno-aminothiourea, has been designed and synthesized in solid phase with microwave by 2,4-dihydroxyacetophenone and aminothiourea. The structure was determined by IR and single X-ray crystallography analysis. The title compound crystallizes in the monoclinic space group C2/c with the cell parameters a=2. 090 0(2) nm, b=0. 792 90(8) nm, c=1. 324 81(14) nm, β=100. 209 0(10)°, F(000)=944, Z=8, V=2.160 7(4) nm3, Dc=1.365 g. cm-3, M,=225.27, R=0.046 0, Rw=0.130 9, S=1.031. The largest difference in peak and hole of electron density are 401 nm^-3 and -247 nm^-3.
Keywords:2  4-dihydroxyacetopheno-aminothiourea  microwave-assisted solid phase synthesis  crystal structure
