Übergangsmetall-thioketon-komplexe. Synthese und strukturaufklärung von tetracarbonyl(diphenylcyclopropenthion)eisen, [C3(C6H5)2S]Fe(CO)4

Diphenylcyclopropenethione reacts with Fe₂(CO)₉ in THF to give tetracarbonyl(diphenylcyclopropenethione)iron (C₃Ph₂S)Fe(CO)₄. The crystal structure was determined by single crystal X-ray analysis. The compound crystallizes in the triclinic space group P$\text{1}$ with lattice constants a 1520.3(5), b 1026.1(3), c 933.5(2) pm; α 120.58(2), β 109.36(2), γ 111.72(2)°; Z 2. The molecule consists of an unchanged diphenylcyclopropenethione ligand coordinated via the sulphur atom to an Fe(CO)₄ group in the axial position. The CS distance is 165.2(7) pm with an FeSC angle of 111.2(2)°.
