octahedral. The copper(II) complex only undergoes a Jahn–Teller distortion below 100 K, and the pink cobalt(II) complex only slowly oxidises to the dark blue cobalt(III) complex. The chiral gallium(III) complex may be resolved by preparative HPLC, and its 1H NMR spectrum has been fully assigned with the aid of two-dimensional methods. The indium-111 and gallium-67 complexes have been examined in vivo and
1,4,7-三氮杂环壬烷-1,4,7-三基三亚甲基三(苯基次膦酸酯)与Co.Ni,Cu和Zn的二价离子形成C 3对称配合物,并与Fe,Co,Ga的三价离子形成结构相似的配合物和在。对于所检查的八个晶体结构中的每一个,配体都具有相同的刚性构象,并形成了一个单一的手性非对映异构体(每个立体原子磷中心处的RRR或SSS)。金属中心周围的几何形状略微扭曲八面体。铜(II)配合物仅在100 K以下经历Jahn-Teller畸变,粉红色的钴(II)配合物仅缓慢氧化为深蓝色钴(III)配合物。手性镓(III)配合物可以通过制备型HPLC拆分,并且其1 H NMR光谱已通过二维方法进行了完全分配。铟111和镓67复合物已在体内进行了检查,并显示出与它们的亲脂性有关的选择性胆汁清除率。
