It belongs to monoclinic system with space group P21/n and crystal cell parameters:a=1.619 9（3）, b=0.680 5（1）, c=2.802 8（6） nm, β=94.15（3）°; V=3.082（1） nm 3, Z=4, Dc=1.289 g/cm3, Mr=589.22, μ（MoKα）=0.750 mm -1, F（000）=1 268. The structure was refined to R=0.057 8 and wR=0.158 1 for 4 447 observed reflections with I≥2σ（I）. The aquo complex is mononuclear with distorted square-pyramidal coordination.展开更多
Salicylaldehyde thiodiacylhydrazone(STZ), 5-bromosalicylaldehyde thiodiacyl hydrazone(BSTZ) and their Cu(Ⅱ) complexes: STZ(Cu) 2 and BSTZ(Cu) 2 were synthesized.

The structures of the ligands and complexes were characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The bacteriostatic test showed that the ligands were more bioactive than the complexes.展开更多

The single-crystal structure of the complex reveals that the crystal belongs triclinic, space group P1 with cell parameters a=0.938 7(4) nm, b=1.124 4(5) nm, c=1.222 3(5) nm, α=99.538(7)°, β=104.049(8)°, γ=113.806(6)°, and Z=2, V=1.093 3(8) nm3. Cu(Ⅱ) ion is coordinated by two 1-phenyl-3-methyl-4-acyl-5-pyrazolone ligands, and one methanol molecule giving a coordination number of five, the coordination polyhedron around Cu(Ⅱ) ion can be described as a square pyramid. Two complex units link to each other through the hydrogen-bonding interactions to form a dimer. Meanwhile, a staircase-like layer structure was built up by offset face-to-face π…π stacking interactions and weak interactions between the dimers.展开更多
