Structural Regularities of the Transition Metal Complexes Containing o-Benzenedithiol （H2bdt）——Synthesis and Structure of Fe3（bdt）3（PBu3n）3

Complex Fe3（bdt）3（PBu3n）3 was synthesized in the presence of PBu3n and the structural regularities in a series of transition metal complexes containing bdtH2 ligand were summarized. The title complex crystallizes in the triclinic space group P-, Mr=1195.19, cell parameters: a=13.283（3）, b=20.115（5）, c=13.156（3）, （?）=90.33（2）, β= 116.47 （1）, γ=92.19（2）°, V=3143.5（2.7）3, Z=2, dc=1.26g/cm3. The structure was solved by direct methods from 4122 unique reflections with I>4σ（I） and reached the final convergence factor of R（Rw） = 0.053 （0.060）. The complex exhibits strong paramagnetism.
