Reaction of the triethylphosphinecarbon disulfide adduct Et3PCS2 with iron(II) aquocations in the presence of the bis(tertiary phosphines) depe or diphos, and NaBPh4 has given the monomeric complexes (BPh4)2, 1, and (BPh4)2 * 0.5(CH3)2CO, 3 (depe = 1,2-bis(diethylphoshino)ethane; diphos = 1,2-bis(diphenylphosphino)ethane).Compound 1 undergoes nucleophilic attack by hydride ion on the coordinated Et3PCS2 ligand to give the dithioformato derivative (BPh4), 2.The structures of compounds 1 and 2 have been determined from counter diffraction X-ray data.Crystal data for 1 are: triclinic, space group P, a 18.583(8), b 14.836(7), c 14.019(7) Angstroem, α 94.38(4), β 102.56(4), γ 103.34(4) deg, Z = 2, R = 0.080.Crystal data for 2 are: monoclinic, space group P21/a, a 28.912(10), b 11.949(6), c 13.386(7) Angstroem, β 94.35(5) deg, Z = 4, R = 0.076.In both structures the iron atom displays a distorted octahedral geometry, being linked to the phosphorus atoms of two depe molecules and to the two sulfur stoms of the zwitterion in compound 1 or of the dithioformato group in compound 2.
