  摘要：

  The two independent formula units of the title compound, [(C18H15P)(2)N][CrCl3(C5H5)], display similar pseudo-tetrahedral anions. The Cr-Cl bond lengths of 2.291(2)-2.318(2)Angstrom are consistent with values from previous studies.

  [CpCrCl2]2(dmpm) to [CpCrCl(dmpm)]+[CpCrCl3]-. The mononuclear adducts have a 15-electron configuration CpCrX2(η1-L-L) with a dangling phosphine ligand, both in the solid state, as shown by an X-ray crystal structure of CpCrCl2(dmpm), and in solution, as shown by 31P-NMR, UV−visible, and EPR spectroscopies. The hypothetical 17-electron configuration where the bidentate L-L ligand adopts a chelating configuration
