| Description | Journal: Angewandte Chemie International Edition In a high‐yield one‐pot synthesis, the reactions of [Cp*M(η5‐P5)] (M=Fe (1), Ru (2)) with I2 resulted in the selective formation of [Cp*MP6I6]+ salts (3, 4). The products comprise unprecedented all‐cis tripodal triphosphino‐cyclotriphosphine ligands. The iodination of [Cp*Fe(η5‐As5)] (6) gave, in addition to [Fe(CH3CN)6]2+ salts of the rare [As6I8]2− (in 7) and [As4I14]2− (in 8) anions, the first di‐cationic Fe‐As triple decker complex [(Cp*Fe)2(μ,η5:5‐As5)][As6I8] (9). In contrast, the iodination of [Cp*Ru(η5‐As5)] (10) did not result in the full cleavage of the M−As bonds. Instead, a number of dinuclear complexes were obtained: [(Cp*Ru)2(μ,η5:5‐As5)][As6I8]0.5 (11) represents the first Ru‐As5 triple decker complex, thus completing the series of monocationic complexes [(CpRM)2(μ,η5:5‐E5)]+ (M=Fe, Ru; E=P, As). [(Cp*Ru)2As8I6] (12) crystallizes as a racemic mixture of both enantiomers, while [(Cp*Ru)2As4I4] (13) crystallizes as a symmetric and an asymmetric isomer and features a unique tetramer of {AsI} arsinidene units as a middle deck. |
