Dialkylchalkogenidverbrückte Carbonylzweikernkomplexe des Typs [M] 2 ER 2 mit M = {CpMn(CO) 2 } und {Cr(CO) 5 }; E = S, Se, Te; R = Me oder R 2 = (CH 2 ) 3 bzw. (CH 2 ) 4 ; Röntgenstrukturanalyse von [CpMn(CO) 2 ] 2 S(CH 2 ) 3 / Dialkylchalcogenide-Bridged Dinuclear Carbonyl Complexes of the Type [M] 2 ER 2 with M = {CpMn(CO) 2 } and {Cr(CO) 5 }; E = S, Se, Te; R = Me or R 2 = (CH 2 ) 3 , (CH 2 ) 4 ; X-Ray-Structure Analysis of [CpMn(CO) 2 ] 2 S(CH 2 ) 3

The reaction of CpMn(CO) 2 THF or Cr(CO) 5 THF with alkylchalcogenides ER 2 (E = S, Se, Te; R = Me or R 2 = (CH 2 ) 3 , (CH 2 ) 4 ) in the molar ratio of 2:1 gives alkylchalcogenide-bridged dinuclear complexes [CpMn(CO) 2 ] 2 ER 2 and [Cr(CO) 5 ] 2 ER 2 . The heteronuclear complex Cp(CO) 2 Mn - (μ-SMe 2 ) -Cr(CO) 5 can be synthesized by reacting CpMn(CO) 2 SMe 2 with Cr(CO) 5 THF. X-ray structure analysis of the compound [CpMn(CO) 2 ] 2 S(CH 2 ) 3 demonstrates the bridging character of the alkylchalcogenides.
