摘要：
The compounds Re-2(DPhF)(3)Cl-3 and Re-2(DPhF)(2)Cl-4 have been prepared and structurally characterized (DPhF =anion of N,N-diphenylformamidine). The former has three bridging DPhF ligands, two equatorial Cl ligands and one axial Cl ligand. The Re-Re distances in two different crystallographic forms are 2.2318(8) Angstrom and 2.2288(9) Angstrom. The second compound has two trans DPhF ligands and the Re2Cl4 unit is planar with Re-Re = 2.177(1) Angstrom, Re-Cl(av) = 2.319(5) Angstrom, Re-N(av)= 2.06(1) Angstrom and Cl-Re-Cl(av)= 106.0(1)degrees.
