posted on 2016-08-15, 18:19 authored by Fei Zhong, Xiaodong Yang, Lingyi Shen, Yanxia Zhao, Hongwei Ma, Biao Wu, Xiao-Juan YangA C3-symmetric hexamine (LH6) based on the triphenylene and ortho-phenylenediamine
(PDAH2) skeletons has been synthesized, and was partially
or fully deprotonated upon treatment with alkali metal agents to afford
amino–amido or diamido coordination sites. Four alkali metal
complexes, the dinuclear [Na2(LH4)(DME)5] (1) and [K2(LH4)(DME)4] (2), trinuclear [K3(LH3)(DME)6] (3), and hexanuclear [Li6(L)(DME)6] (4), were obtained and used in transmetalation/ligand
exchange with other metals. The hexalithium salt of the fully deprotonated
ligand, [Li6L], reacted with heavier group
14 element halides to yield three tris(N-heterocyclic tetrylenes),
the germylene [Ge3(L)] (5), stannylene
[Sn3(L)] (6), and plumbylene
[Pb3(L)] (7). The synthesis and
crystal and electronic structures of these compounds are reported.
