Solvothermal Synthesis,Crystal Structure and Characterization of a New Binuclear Nickel(Ⅱ)Complex with 2-(4-Methylbenzoyl)benzoic Acid

A new binuclear nickel(Ⅱ) complexNi_2(MBBA)_2(HPT)_2(H_2O)_2]·2H_2O (1) was synthesized with nickel hydroxide,2-(4-methylbenzoyl)benzoic acid (HMBBA) and 3-(pyridin-2-yl)-1H-1,2,4-triazole (HPT).It crystallizes in the monoclinic space group P2_1/n with a=14.5902(13),b=8.8191(6),c=17.6120(14)?,β=110.830(9)o,V=2118.0(3)?~3,M_r=958.26,D_c=1.503 g/cm~3,Z=2,μ(Mo Ka)=0.959,F(000)=992,the final GOOF=1.001,R=0.0353 and w R=0.09864.Each central Ni(II) ion is coordinated by two oxygen and three nitrogen atoms,forming a distorted square pyramidal geometry.The XRD,TG,spectrum analysis and magnetic properties of 1 were studied.
