| Abstract: | The synthesis and crystal structure of multidentate ligand 4-(2,5-dihydroxy-1,4-benzoquinonyl)- semicarbazide are reported in this paper. The title compound is orthorhombic with space group P212121, a=13.221(6),b=17.709(5),c=5.347(4)? V=1252.0(1)3,Z=4,F(000)=568, Dx=1.434g/cm3,Mr=270.25, m (Mo-Kα)= 1.16 cm-1. The crystal structure was determined by direct methods, and refined by full-matrix least-squares method for the final R=0.0319 and wR=0.0748.There are two intermolecular hydrogen bonds between the 4-(2,5-dihydroxy-1,4-benzoquinonyl)-semicarbazide and DMF. 4-(2,5-dihydroxy-1,4-benzoquin onyl)- semicarbazide is a coupling compound of two conjugate chains. |
