  Synthesis and Characterization of Cubane‐Like Cr ₄ E ₄ (E = S, Se) Clusters − Molecular Structures of (η ⁵ ‐RC ₅ H ₄ ) ₄ Cr ₄ E ₄ (E = S, R = MeCO, MeO ₂ C, EtO ₂ C; E = Se, R = H)

  摘要：

  AbstractTreatment of the Cr−Cr singly‐bonded dimers [η5‐RC5H4Cr(CO)3]2 (1, R = MeCO; 2, R = MeO2C; 3, R = EtO2C) with excess sulfur in refluxing THF gave the cubane Cr4S4 clusters (η5‐RC5H4)4Cr4S4 (4, R = MeCO; 5, R = MeO2C; 6, R = EtO2C). The cubane Cr4S4 cluster 4 reacted with excess 2,4‐dinitrophenylhydrazine to produce the hydrazone derivative [η5−2,4‐(NO2)2C6H3NHN=C(Me)C5H4]4Cr4S4 (7). The singly‐bonded dimers of [η5‐RC5H4Cr(CO)3]2 (8, R = Me; 9, R = EtO2C), in the presence of excess selenium, reacted similarly to the linear Cr2Se complexes [η5‐RC5H4Cr(CO)2]2Se (10, R = Me; 11, R = EtO2C), which reacted with an equimolar quantity of selenium to afford the cubane Cr4Se4 clusters (η5‐RC5H4)4Cr4Se4 (12, R = Me; 13, R = EtO2C). A particularly interesting phenomenon is the cross‐assembled reaction of the linear Cr2Se complexes [η5‐MeC(O)C5H4Cr(CO)2]2Se (14) and [CpCr(CO)2]2Se (15) in the presence of excess selenium in THF that gave rise to a series of cubane Cr4Se4 clusters [η5‐MeC(O)C5H4]nCp4−nCr4Se4 (16, n = 0; 17, n = 1; 18, n = 2; 19, n = 3; 20, n = 4). The possible pathway for the cross‐assembled reaction is suggested. Furthermore the new clusters were characterized by elemental analysis and spectroscopy, and in the case of 4−6 and 16 also by X‐ray diffraction techniques. (© Wiley‐VCH Verlag GmbH & Co.
