Homoleptic complex La(InMe4)3 is obtained from the respective aluminium congener La(AlMe4)3 via a donor-assisted tetramethylaluminate/tetramethylindate exchange protocol. Compound La(InMe4)3 exhibits interesting thermal lability as well as distinct cluster formation like La4In7(C)(CH)2(CH2)2(CH3)19 and La5In9(CH)6(CH3)24 upon addition of an excess of donor or thermal treatment. The neutral potentially tridentate ligand Me3TACN (1,4,7-trimethyl-1,4,7-triazacyclononane) is used to investigate into donor-triggered intermediates. Compound La(InMe4)3 is the first crystallographically characterized homoleptic rare-earth-metal tetramethylindate and may readily be used as precursor for follow-up chemistry distinct from La(AlMe4)3 and La(GaMe4)3.

同相异型稀土金属四甲基萌酸酯


同源复合物 La（InMe4）3 通过供体辅助的四甲基铝酸盐/四甲基酯交换方案从相应的铝同系物 La（AlMe4）3 获得。化合物 La（InMe4）3 在添加过量的供体或热处理后表现出有趣的热不稳定性以及独特的团簇形成，如 La4In7（C）（CH）2（CH2）2（CH3）19 和 La5In9（CH）6（CH3）24。中性潜在三齿配体 Me3TACN （1,4,7-三甲基-1,4,7-三氮杂环壬烷） 用于研究供体触发的中间体。化合物 La（InMe4）3 是第一个晶体学表征的同源稀土金属四甲基萌酸盐，可以很容易地用作不同于 La（AlMe4）3 和 La（GaMe4）3 的后续化学的前体。
