Chlorine-Induced Hydrogen-Bonding Network of A Novel Dimer Based on Nickel and Tridentate Ligand： 3-Hydrazine-4-amino-1,2,4-Triazole

The reaction of NiCl2 and 3-hydrazine-4-amino-1,2,4-triazole （Hatr） in the mixed solvent of EtOH and H2O yielded a dimer compound （[Ni2（Hatr）2（H2O）2（EtOH）2Cl2]ClzoEtOH） with water and EtOH molecules coordinated to nickle ions. It crystallized in trigonal space group R-3, a=b=29.67（1） A, c=8.95（7） A,...

Description
Summary:The reaction of NiCl2 and 3-hydrazine-4-amino-1,2,4-triazole （Hatr） in the mixed solvent of EtOH and H2O yielded a dimer compound （[Ni2（Hatr）2（H2O）2（EtOH）2Cl2]ClzoEtOH） with water and EtOH molecules coordinated to nickle ions. It crystallized in trigonal space group R-3, a=b=29.67（1） A, c=8.95（7） A, β= 120（1）°, as determined by single-crystal X-ray diffraction. Then, they were fully characterized by the IR spectroscopy, differential scanning calorimetry （DSC）, thermogravimetry （TG）, and elemental analysis.
