Rezumat

Abstract: Two new bis- and tris(solvatomorphs) [Ni(DAnH)2]·0.25H2O (I) and [Ni(DAnH2)3]Cl2· 6CH3OH (II) are synthesized by the reaction of dianilineglyoxime (DAnH2) with nickel(II) chloride under different conditions. The molecular structures of complexes I and II are determined by X-ray diffraction analysis (CIF files CCDC nos. 1998570 and 1998571, respectively). Complex I taken in optimally selected concentrations exerts the stimulation effect on the synthesis of proteases of the biotechnologically significant micromycete strain Fusarium gibbosum CNMN FD 12 increasing the activity of acidic proteases by 83.0% and that of neutral proteases by 68.2% compared to the control value. Complex I can be considered as a potential biostimulator of enzyme formation for some strains of mycelium fungi.
