TRANSITION METALS COORDINATION COMPOUNDS WITH BENZOHYDRAZID

Benzohydrazid as a ligand in coordination compounds has been characterized. Benzohydrazid and its complexes potential applications have been shown. A general description coordinate to the metal) has been done. The composition and structure of d-metals benzohydrazid complexes with different anions have been discussed. Halide, sulfate, nitrate, thiocyanate, perchlorate, nitrite, acetate complexes have been characterized for various central ions. Examples of complexes with benzohydrazid ketone and enol forms have been given. Complexes with solvate molecules of water and methanol have been considered. The general characteristics of the structures according to X-ray structural analysis are presented for some compounds. The peculiarities of benzohydrazid interaction with copper (II) salts with various anions have been denoted. The data on the vanadium complexes including benzohydrazid different degree of deprotonation are presented. The change of the way of benzohydrazid binding with mercury depending on the anion has been shown. Examples of bimetallic and mixed-ligand complexes have been given. The structure of the complexes [Co(НL)(Mal)(H2O)2]H2O (H2Mal– malonic acid), and [Co(НL)3](OH)Cl(Н3Ssal)H2O (Н3Ssal – 5-sulfosalicylic acid) is described. The aspects of the biological activity of some complexes (bactericidal, fungicidal, cytotoxic) have been considered.
