Four new thallium(I) coordination polymers, [TlBt]n (1) (Hbt = 5-phenyltetrazole), [TlBbt] (2) (Hbbt = 5-(4-bromobenzyl)tetrazole), [Tl2Bdt]n (3) (H2bdt = 5,5′-benzene-1,4-diylbistetrazole), [Tl2Pht·H2O]n and [TlBet] (4), (Hbet = 5-(benzyl)tetrazole) have been synthesized and characterized. The single-crystal X-ray data shows that, in compounds 1–3, the coordination sphere of the Tl(I) ion is the same
四种新的coordination (I)配位聚合物[TlBt] n(1)(Hbt =5-苯基四唑),[TlBbt](2)(Hbbt =5-(4-溴苄基)四唑),[Tl 2 Bdt] n(3)(H 2 bdt =5,5'-苯-1,4-二基双四唑),[Tl 2 Pht·H 2 O] n和[TlBet](4),(Hbet =5-(苄基)四唑)已被合成和表征。单晶X射线数据表明,在化合物1-3中,Tl(I)离子的配位域是相同的,并且被六个四唑酸酯环包围。在化合物4中,一个al原子与四唑酸酯基团具有三个相互作用,并且与苯环紧密的Tl I ⋯π(芳族)接触。此外,在所有情况下,单晶X射线数据显示出与价壳电子孤对Tl I相同的立体化学活性。在化合物1和3中,一维的Tl I ITl I相互作用很强。通过简单的煅烧方法,所有这四种化合物已被用作制备氧化al(III)纳米颗粒的新前体。通过粉末XRD衍射表征氧
