A new thiosemithiocarbazone ligand C6H4(OH) CHN(NH) S (NH2) named H4L have been isolated and characterized by single crystal X ray diffraction. H4L compound crystallizes in the monoclinic system, space group C2c with a = 28.1975(4) A, b = 6.71768(10) A, c = 19.4249(3) A, beta = 94.6290(17), V = 1737.84(14) A3 and Z = 4. The asymmetric unit of H4L1is consisted ofa dimeric structure of two molecules of C6H4 (OH) CHN (NH)S(NH2). Each monomer contains one intramolecular OH N [NH(4)O(3) =2.553A] hydrogen bond which comes from the hydrogen atom of OH group and the nitrogen atom of CN group and NHS[N(4)H(4A)S(1)=2.699A] intermolar hydrogen bond, acetic acid type, interacting electrostatically with two semicarbazone ligands. In supramolecular vue, organic ligands are linked via S (H,H)O bifurcated hydrogen bonds or NHO hydrogen bonds. Structural characterization were completed by elemental analysis,infrared and 1H, 13C{1H} spectroscopies and which corroborate the X-ray elucidations.
