an intramolecular interaction between the mercury(II) ion and the phenyl ring. Such an interaction is only observed for series (1) when X = NH2 or S− and n = 1 or 2. In the case of the N-bound methyl(L-tyrosinato)mercury(II), there is fairly good agreement between the crystal structure and that observed in solution, as estimated from the anisotropic shift and conformational analysis based on the backbone
摘要甲基汞(II)离子的配合物是通过几个具有苯环的同源配体系列制备的:(1)C6H5(CH2)nX(X = NH2,S-,n = 1,2,3; X = CO −2,n = 0,1,2)和(2)pR-C6H4(CH2)n-1 CH(NH2)CO-2(R = H,n = 2,3; R = OH,n = 2) 。[MeHg] + 1H nmr共振的高场移的观察结果被解释为由于汞(II)离子与苯环之间的分子内相互作用而引起的各向异性屏蔽效应。仅当X = NH2或S-且n = 1或2时,才在系列(1)中观察到这种相互作用。晶体结构和在溶液中观察到的晶体结构,这是根据各向异性位移和基于骨架邻位偶合常数的构象分析估计的。
