Thiosemicarbazones, semicarbazones and their derivatives are widely used in coordination chemistry due to their abilities to generate with transitional metals biological - active coordination compounds displaying different composition, structures and properties. Aiming at enlarging the structural information of coordination compounds with potential medical applications, two new complexes with the following formula [Co2(HL)3(L)]ClO4 ∙ 3H2O and [Cu(HL1)(H2O)2]NO3 (H2L = salicylaldehyde thiosemicar-bazone, H2L1 = 3,5-dicloro-salicylaldehyde semicarbazone). The complexes have been synthesised upon reacting stoechiometric amounts of ethanolic solution of cobalt (II) perclorate or copper (II) nitrate with H2L or H2L1 ligands. The exact composition and structure of the obtained substances have been determined by elemental analysis, IR spectroscopy, thermogravimetric study and single crystal X-ray diffraction technique.
