The title compounds were isolated and their structures determined by crystallographic methods. [Fe2I4(dppe)2] (1) and [Fe2(SR)4(dppe)2] (2) formdimeric complexes with the bidentate phosphane binding to different iro n atoms. The resulting ten-membered rings of both compounds exhibit a nearly identical conformation. The central FeS2P2 units of the mononuclearcomplexes [Fe(SR')2(dppp)2] (3) and [Fe(SR)2(PMePh2)2] (4) show like 2 large deviations from ideal C2v symmetry with bonding angles around the central iron atom ranging from 97.2, 92.5, and 96.5° (angle P-Fe- P in 2, 3, and 4, respectively) to 129.0, 129.9, and 133.6° (angle S-Fe-S in 2, 3, and 4, respectively).
