Synthesis, Characterization and Kinetic Study of Monomeric Complexes of Cyclohexane-1, 2- bis (Thiosemicarbazone) with Cobalt (II), Nickel (II) and Copper (II)

Abstract


Cyclohexane-1,2-bis(thiosemicarbazone) (CHTSC) was synthesized via the condensation reaction of cyclohexane-1,2-dione and thiosemicarbazide. Series of metal complexes of the prepared lig-and, of general formula [M(CHTSC)(NO3)2], were reported. The prepared coordination complex-es were characterized and their structures elucidated using different techniques. These showed that all complexes are octahedral geometries. The kinetics of the formation of these complexes have been investigated using stopped-flow spectrophotometry. These studies revealed that the reactions are completed on the second’s timescale with 1st-order dependence (either on the con-centration of metal salt or on the concentration of CHTSC).
