nuclear medicine with similar properties. In this study, new diamido dipyridino (N(4)) water-soluble ligands (2-C(5)H(4)NCH(2)NHCO)(2)CH(2), 1 (L(1)H2), (2-C(5)H(4)NNHNHCO)(2)CH(2), 2, and [2-C(5)H(4)N(+)(O)(-)CH(2)NHCO](2)CH(2), 3, were synthesized. Reaction of L(1)H2 with ReOCl(3)(PPh(3))(2) resulted in the novel six-coordinated rhenium(V) complex, trans-ReO(L(1))(OEt), 4. The complex was characterized
and和tech因其在核医学中具有相似性质的有用应用而闻名。在这项研究中,新的重氨基二吡啶(N(4))水溶性配体(2-C(5)H(4)NCH(2)NHCO)(2)CH(2),1(L(1)H2) ,(2-C(5)H(4)NNHNHCO)(2)CH(2),2和[2-C(5)H(4)N(+)(O)(-)CH(2)合成了NHCO](2)CH(2),3。L(1)H2与ReOCl(3)(PPh(3))(2)的反应产生了新颖的六配位rh(V)络合物,即Trans-ReO(L(1))(OEt),4。该配合物通过分光光度法进行了表征,其X射线晶体学分析表明,is以扭曲的八面体几何形状与配体的四个氮原子以及去质子化的乙醇和氧代基团的两个氧原子配位。在解决方案中,将复合物4转换为新的复合物5,证明是双核复合物mu-oxo [ReO(L(1))](2)O。1与[n-Bu(4)N] [ReOCl(4)]的反应生成中
