| Abstract: A novel methyltrioxorhenium(Ⅶ) (MTO) complex was synthesized by the reaction of MTO with Schiff-base ligand obtained by the condensation of 2-pyridinecarboxaldehyde with 4-bromoaniline in methanol. The complex was characterized by NMR, IR, MS, elemental analysis and X-ray diffraction single crystal structure analysis. The results showed that the crystal belongs to monoclinic, space group P21/n with a=0.965 70(19) nm, b=1.410 6(3) nm, c=1.080 4(2) nm, β=109.20(3)°, V=1.390 0(5) nm3, Mr=510.36, Z=4, Dc=2.439 g·cm-3, F(000)=952 and final R1=0.034 4, wR2=0.076 1. The crystal structure indicates that the Re(Ⅶ) atom is coordinated with both nitrogen atoms from the Schiff-base. CCDC: 740159. |
