  摘要：

  AbstractA metal‐rich niobium oxyiodide was prepared by soft reduction of NbI4. The structure of the new compound Nb4OI10 was determined by single‐crystal X‐ray diffraction and contains a rectangular Nb4(μ4‐O) cluster that is interconnected into layers by iodide ligands. The local structure of the Nb4OI10 cluster bears a close relationship to a defect Nb6I11 structure. The two‐dimensional van der Waals material Nb4OI8I4/2] is a small band‐gap semiconductor (<1 eV), as analysed by electrical conductivity measurements, photoresponse, experimental band gap determination, and band structure calculation.

  bismethylsilicon carbodi-imides have been prepared in high yield by halide metathesis reactions with lead(II), silver(I), or silicon(IV) species. The new derivatives in the series of general formula (MenH3 –nMN:)2C (MSi or Ge; n= 1, 2 or 3) have been characterised by 1H n.m.r., i.r., and Raman spectroscopy as well as mass spectrometry and cleavage reactions.
