Salicylaldehyde 4-allylthiosemicarbazone 2-HO-C6H4-CH=N-NH-C(S)-NH-CH2-CH=CH2 possesses a wide range of donor atoms and forms with transition metal ions coordination compounds with various composition and structure. These complexes show selective antitumor activity. It was determined that in many cases biological activity of these compounds consists with their structure. Therefore, the synthesis and the determination of composition of new coordination compounds of this thiosemicarbazide derivatives are of both scientific and practical interest. The aim of this work is the synthesis and the determination of crystal structure features of dimethylsulfoxide-N-allyl-2-(2-hydroxybenzylidene)hydrazinecarbothioamido)copper(II) [Cu(DMSO)L]NO3 (I) (space group P-1, a = 4.450 Å, b = 12.553 Å, c = 17.092 Å, α = 108.340, β = 93.070, γ = 91.080) and dimethylformamide-N-allyl-2-(2-hydroxynaphthalen-1-yl)-methylenhydrazinecarbothioamido)copper(II) [Cu(DMF)L1]NO3 (II) (space group P-1, a = 7.790 Å, b = 11.766 Å, c = 23.534 Å, α = 79.450, β = 85.230, γ = 77.910) nitrates, where HL and HL1 are salicylaldehyde and 2-hydroxy-1-naphtaldehyde 4-allylthiosemicarbazones, respectively. The X-ray diffraction analysis has been used for structural characterization of studied compounds. In both complexes, the copper atom is tetracoordinated with a square planar geometry where the thiosemicarbazone ligand coordinates to the metal atom in a tridentate manner while the forth coordination site is occupied by the oxygen atoms of the solvent molecules. In the crystal the solvent molecules and NO3-groups join the complexes into the chains along  and  directions (Fig. 1).
