STRUCTURAL REGULARITIES OF THE TRANSITION-METAL COMPLEXES CONTAINING O-BENZENEDITHIOL (H2BDT) - SYNTHESIS AND STRUCTURE OF FE3(BDT)3(PBUN3)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 bdtH-2 ligand were summarized. The title complex crystalli zes in the triclinic space group P-1BAR, Mr = 1195.19, cell parameters : a = 13.283(3), b = 20.115(5), c = 13.156(3) angstrom, alpha = 90.33( 2), beta = 116.47 (1), gamma = 92.19(2)-degrees, V = 3143.5(2.7)angstr om3, Z = 2, d(c) = 1.26 g/cm3. The structure was solved by direct meth ods from 4122 unique reflections with I>4sigma(I) and reached the fina l convergence factor of R(Rw) = 0.053 (0.060). The complex exhibits st rong paramagnetism.
