- 中文摘要: The crystal and molecular structures have been determined by single-crystal X-ray methods for the binuclear metal ions (II) complexes of 7-azaindole (1H-pyrrolo(2, 3-b) pyridine, C/sub 7/H/sub 6/N/sub 2/ denoted by HL), Cu/sub 2/( CH/sub 3/CO/sub 2/) /sub 2/L/sub 2/(HL)/sub 2/ and Ni/sub 2/L/ sub 4/.bcdot.2DMF. The dark green crystal of Cu/sub 2/(CH/ sub 3/CO/sub 2/)/sub 2/L/sub 2/(HL)/sub 2/ was found to crystallize in the monoclinic space group P2/sub 1//n with a=9.566(2), b=12.752(2),c=12. 852(4).ANG.,.beta.=99.23(3).degree., V=1547.ANG.,Z=2, the final R=0.062 and Rw=0.053 for 1488 observations from 2722 unique reflections. The Cu-Cu distance is 2.747(2),Cu-N(L/sup -/, bridge) is 1.966(7), Cu-N( HL,axial) is 2.229(8), and Cu-O is 2. 031(6).ANG.. The red crystal of Ni/sub 2/L/sub 4/.bcdot.2DMF was found to crystallize in the triclinic space group P.1bar. with a=8.907( 5), b=9.462(2), c=10.217(2).ANG.,.alpha.=90.48(2), .beta.= 91.09(3), .gamma.=110.69(3).degree.,V=805.ANG./sup 3/, Z=1, the final R=0.063 and Rw=0.069 for 1489 observations from 2834 unique reflections. The Ni-Ni distance is 2.594(2), Ni-N is 1.905 (7).ANG.. These two molecules lie on crystllographic inversion centers and exhibit ligand disorder.
