Tripodal ligands with main group bridghead units are well established in coordination chemistry and single-site organometallic catalysis. Although a large number of tris(2-pyridyl) main group ligands [E(2-py)] (E = main group element, 2-py = 2-pyridyl) spanning across the whole p-block are now synthetically acessible, only limited work has been done on the coordination chemistry on the tris(2-pyridyl) group 15 ligands for the heavier elements (As, Sb). In the current study we investigate the coordination chemistry of the ligand family E(6-Me-2-py) (E = As, Sb) and of the As(v) ligand O[double bond, length as m-dash]As(6-Me-2-py). The air- and mositure-stability of all of these main group ligands makes them especially attractive in future catalytic applications.
具有主族桥头单元的三脚架配体在配位化学和单中心有机金属催化领域已得到广泛应用。尽管目前已能通过合成获得大量跨越整个p区的三（2-吡啶基）主族配体[E(2-py)]（E = 主族元素，2-py = 2-吡啶基），但对于较重元素（As、Sb）的三（2-吡啶基）第15族配体的配位化学研究却非常有限。在本研究中，我们探究了配体家族E(6-Me-2-py)（E = As、Sb）以及As(V)配体O[双键，长度为m短划线]As(6-Me-2-py)的配位化学。所有这些主族配体对空气和湿气的稳定性使其在未来催化应用中极具吸引力。
