The syntheses and infrared spectra of a series of mono(tetracarbonylcobalt)tin(IV) derivatives of the general formula R_nX_{3_n}SnCo(CO)₄ [R = C₆H₅; X = Cl, Br, I; n = 0, 1, 2] are reported. Several triphenylphosphine complexes are also described. Assignments are suggested for the carbonyl stretching bands. Cobalt carbonyl reacts with tin(II) fluoride to form FSn-[Co(CO)₄]₃ and with tin(II) acetate to yield (CH₃CO₂)₂Sn[Co(CO)₄]₂ and (CH₃CO₂)Sn[Co(CO)₄]₃. The preparation of Sn-[Co(CO)₄]₄ is also reported.
