| Abstract: Employing N-acetylsalicylhydrazide (H3ashz), imidazole (imdz) as mixed ligands, a new trinuclear nickel(Ⅱ) compound [Ni3(ashz)2(imdz)2]·2DMF has been synthesized and characterized by elemental analysis, IR and X-ray diffraction structural analysis. Crystal data: monoclinic, space group P21/n with a=1.028 0(2) nm, b=1.499 2(3) nm, c=1.523 1(5) nm, β=114.16(2)°, V=2.140 1(9) nm3, Z=2, Dc=1.516 g·cm-3, μ=1.372 mm-1, F(000)= 1 012. In the title complex, two μ2-bridged ashz3- ligands bound to three nickel centers in a linear array. The three nickel atoms are directly linked together by two trans diazine (N-N) bridges, with the neighboring nickel atomic separations of 0.462(1) nm. CCDC: 902486. |
