- 中文摘要: Electron-delocalized quinoid-like complexes--- [ Ru/sup II/(bipy)/sub 2/(N-ph-bqdi) ] /sup 2+/, cis- [ Co/sup III/(N-ph-s-bqdi)/sub 2/(py) ] /sup +/ and trans- [ Ni/sup II/(N-ph-s-bqdi)/sub 2/ ] (N-ph-bqdi=N-phenyl-o- benzoquinonediimine, N-ph-s-bqdi =N-phenyl-o-semi- benzoquinonediimine) were synthesized that display reversible multi-electron redox couples. The respective cis- and trans-conformation of the Co and Ni complexes are controlled by the steric effect of the substituent phenyl group. The Ni complex forms one-dimensional stacks in crystals. The crystal and molecular structures of three compounds are reported. [ Ru(bipy)/sub 2/(N-ph-bqdi) ](PF/sub 6/)/sub 2/: space group P2/sub 1//c, a=13.292(2), b=18.785(4), c=13.959(2).ANG.; . beta.=97.42(1).degree., V=3456(1).ANG./sup 3/, Z=4, Rf=0.047, Rw=0.044; cis- [ Co(N- ph-s-bqdi)/sub 2/(py) ] .bcdot.(OAc).bcdot.(H/sub 2/O): space group P2/sub 1//n, a=12.752(4), b=13.303(2), c=16.683(3).ANG.; .beta.=102.27(2).degree., V=2765(1).ANG. /sup 3/, Z=4, Rf=0.035, Rw=0.035; and trans- [ Ni(N-ph- s-bqdi)/sub 2/ ] : space group P-1, a=9.771(2), b=10.417(1), c=11.541(2).ANG.; .alpha.=92.24(1), .beta.=104.04(1),.gamma.=117.94(1).degree., V=990.6(3).ANG./sup 3/, Z=2, Rf=0.030, Rw=0.031.
