摘要: The phenol-based compartmental ligands of the “end-off” type, 2,6-bis{N-[2-(dimethylamino)ethyl]iminomethyl}-4-methylphenol (HL1), 2-{N-[2-(dimethylamino)ethyl]iminomethyl}-6-{N-methyl-N-[2-(dimethylamino)ethyl]aminomethyl}-4-bromophenol (HL2), 2,6-bis{2-[(2-pyridyl)ethyl]iminomethyl}-4-methylphenol (HL3) and 2-[N,N-di(2-pyridylmethyl)aminomethyl]-6-{N-[2-(dimethylamino)ethyl]iminomethyl}-4-methylphenol (HL4), have formed dinuclear zinc complexes: [Zn2(L1)(AcO)2]PF6 (1), [Zn2(L1)(NCS)3] (2), [Zn2(L2)(AcO)2]PF6 (3), [Zn2(L2)(NCS)3] (4), [Zn2(L3)(AcO)2]PF6 (5), [Zn2(L3)(NCS)3] (6), [Zn2(L4)(AcO)2]ClO4 (7), [Zn2(L4)(AcO)(NCS)2] (8) [Zn2(L4)(NCS)3] (9). crystal structures 1, 5•(DMF)0.5(2-PrOH)0.5, 7•CHCl3, 8•(2-PrOH) 9•3CHCl3 been determined. Complexes 1 5•(DMF)0.5(2-PrOH)0.5 a di-μ-acetato-μ-phenolato-dizinc(II) core comprised two square-pyramidal Zn centers. 7•CHCl3 has similar core, but it is one pseudo-octahedral Zn. 8•(2...
