General Description

Hafnium oxychloride, also known as HfOCl, is a chemical compound consisting of hafnium, oxygen, and chlorine. It is a white crystalline solid that is soluble in water and has a melting point of approximately 500°C. Hafnium oxychloride is commonly used as a precursor in the production of thin films for electronic devices, such as capacitors and resistors. It is also utilized as a catalyst in organic synthesis and as a reagent in chemical reactions. Additionally, hafnium oxychloride is used in the production of other hafnium compounds and as a component in nuclear reactors and high-temperature applications due to its high melting point and thermal stability.

Synthesis, characterization and biological study on Cr3+, ZrO2+, HfO2+ and UO22+ complexes of oxalohydrazide and bis(3-hydroxyimino)butan-2-ylidene)-oxalohydrazide

Cr3+, ZrO2+, HfO2+ and UO22+ complexes of oxalohydrazide (H2L1) and oxalyl bis(diacetylmonoxime hydrazone) [its IUPAC name is oxalyl bis(3-hydroxyimino)butan-2-ylidene)oxalohydrazide] (H4L2) have been synthesized and characterized by partial elemental analysis, spectral (IR; electronic), thermal and magnetic measurements. [Cr(L1)(H2O)3(Cl)]·H2O, [ZrO(HL1)2]·C2H5OH, [UO2(L1)(H2O)2] [ZrO(H3L2)(Cl)]2·2H2O, [HfO(H3L2)(Cl)]2·2H2O and [UO2(H2L2)]·2H2O have been suggested. H2L1 behaves as a monobasic or dibasic bidentate ligand while H4L2 acts as a tetrabasic octadentate with the two metal centers. The molecular modeling of the two ligands have been drawn and their molecular parameters were calculated. Examination of the DNA degradation of H2L1 and H4L2 as well as their complexes revealed that direct contact of [ZrO(H3L2)(Cl)]2·2H2O or [HfO(H3L2)(Cl)]2·2H2O degrading the DNA of Eukaryotic subject. The ligands and their metal complexes were tested against Gram's positive Bacillus thuringiensis (BT) and Gram's negative (Escherichia coli) bacteria. All compounds have small inhibitory effects.
