CpCr (NO) (CO) _2 reacts with Fe (C_5H_4S) _2S to form the oxidation-reduction product CpCr (NO) (SC_5H_4) _2Fe (1). Dibasic ferrocene CpM (NO) (EC_5H_4) _2Fe [M = Mo, E = S (2a) and Se (2b); M = W and E = S (4a) and Se (NO) (SC_5H_4) _2Fe (3), Cp_2Mo (SeC_5H_4) _2Fe (6) and Cp_2W (SC_5H_4) _2Fe (7) (M = Mo, W), [CpMo (NO) I_2] _2 or Cp_2MCl_2 (M = Mo, W). The ternary hetero-atom ferrocene compound [CpCr (NO) 2] 2 (EC_5H_4) _2Fe [E = S (8a), Se (8b)] consists of Fe (C_5H_4ELi) _2 · 2THF (E = S, Se) Twice the molar amount of CpCr (NO) _2I reaction. The ferrocene ionic compound [CpMo (NO) (SC_5H_4) _2Fe] ~ + BF_4 ~ - (5) was obtained by the oxidation of 2a with AgBF_4. The new compounds were characterized by elemental analysis, IR, ~ 1H and ~ (13) C NMR spectra and EI-MS.
