當一具有雙配位之單陰電性配位基 2-(dimethylaminomethyl)pyrrole(LH)與WCl4(=NPh)(Et2O)和W(=NtBu)2(NHtBu)2反應時可分別產生WCl3(=NPh)(L)和[W(=NtBu)2L]2O。他們可經由核磁共振及X光結構法來鑑定。當更進一步讓0[W(=NtBu)2L]2O與少量之H2O反應後可產生一鎢群W4O6(=NtBu)4L4而此化合物亦可經由核磁共振光普及X光結構法還鑑定。 The reactions of monoanionic bidentate 2-(dimethylaminomethyl)pyrrole(LH) with WCl4(=NPh)(Et2O) and W(=NtBu)2(NHtBu)2 yield WCl3(=NPh)(L) and [W(=NtBu)2L]2O, respectively. Their NMR spectroscopies and X-ray structures are characterized. Further reaction of [W(=NtBu)2L]2O with trace of H2O generates a tungsten cluster, W4O6(=NtBu)4L4 and the compound has been characterized by NMR spectroscopies and X-ray structure determination.
