Multinuclear Alkali Metal Complexes of a Triphenylene-Based Hexamine and the Transmetalation to Tris(N-heterocyclic tetrylenes) (Ge, Sn, Pb) ZhongFei YangXiaodong ShenLingyi ZhaoYanxia MaHongwei WuBiao YangXiao-Juan 2016 A <i>C</i><sub>3</sub>-symmetric hexamine (<b>LH</b><sub><b>6</b></sub>) based on the triphenylene and <i>ortho</i>-phenylenediamine (PDAH<sub>2</sub>) 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 [Na<sub>2</sub>(<b>LH</b><sub><b>4</b></sub>)­(DME)<sub>5</sub>] (<b>1</b>) and [K<sub>2</sub>(<b>LH</b><sub><b>4</b></sub>)­(DME)<sub>4</sub>] (<b>2</b>), trinuclear [K<sub>3</sub>(<b>LH</b><sub><b>3</b></sub>)­(DME)<sub>6</sub>] (<b>3</b>), and hexanuclear [Li<sub>6</sub>(<b>L</b>)­(DME)<sub>6</sub>] (<b>4</b>), were obtained and used in transmetalation/ligand exchange with other metals. The hexalithium salt of the fully deprotonated ligand, [Li<sub>6</sub><b>L</b>], reacted with heavier group 14 element halides to yield three tris­(N-heterocyclic tetrylenes), the germylene [Ge<sub>3</sub>(<b>L</b>)] (<b>5</b>), stannylene [Sn<sub>3</sub>(<b>L</b>)] (<b>6</b>), and plumbylene [Pb<sub>3</sub>(<b>L</b>)] (<b>7</b>). The synthesis and crystal and electronic structures of these compounds are reported.
