chloride. One form of the related iodide (2) is triclinic and isomorphous with the above chloride; selected bond distances are TeI 2.937(1), TeC 2.095(18) and TeN 2.260(10) Å. A second form of the iodide (3) is monoclinic (Z = 4) and yields more accurate parameters: TeI 2.917(11), TeC 2.112(6), TeN 2.268(5) Å. The synthesis of the new organyltellurium(II) iodides are given together with those of
确定了标题化合物的结构。的2-(2-吡啶基)phenyltellurium(II)氯化物(结构1)是三斜晶系和由具有平均接合距离超过六个独立的分子离散分子TeCl2.606(11),TeC2.077(7)和短的Te…N相互作用距离为2.205(11)Å。将“纯”化合物中的分子结构与先前报道的分子结构进行了比较,在该结构中,该分子与氯化对乙氧基苯基汞(II)形成2:1的包合物。相关碘化物(2)的一种形式是三斜晶的并且与上述氯化物同晶。选定的键距为TeI2.937(1),TeC2.095(18)和TeN2.260(10)Å。碘化物(3)的第二种形式是单斜晶系(Z= 4)并得出更准确的参数:TeI2.917(11),TeC2.112(6),TeN2.268(5)。给出了新的有机碘化碘鎓盐与“ RTeI”的合成,其中R = 2-(2-吡啶基)苯基-或2-苯基偶氮苯基-:建议在光谱学
