A series of polyoxomolybdate‐incorporated organometallic complexes has been obtained by reaction of [MBr(CO) 5 ] or solvated {M(CO) 3 } + ions (M=Mn or Br) with ( n Bu 4 N) 2 [Mo 2 O 7 ] in methanol, sometimes in the presence of triols of the type RC(CH 2 OH) 3 (R=Me or CH 2 OH). Their molecular structures are related to those of previously described polyoxoalkoxomolybdates through the formal replacement of fac ‐{MoO 2 (OR)} + units by topologically equivalent fac ‐{M(CO) 3 } + units. Representative pairs of structurally related clusters include [Mo 2 O 6 (OMe) 4 {Re(CO) 3 } 2 ] 2− and [Mo 4 O 10 (OMe) 6 ] 2− , [Mo 2 O 4 {MeC(CH 2 O) 3 } 2 {Mn(CO) 3 }] − and [Mo 3 O 6 (OMe){MeC(CH 2 O) 3 } 2 ] − , [Mo 2 O 4 {HOCH 2 C(CH 2 O) 3 } 2 {Mn(CO) 3 } 2 ] and [Mo 4 O 8 (OEt) 2 {MeC(CH 2 O) 3 } 2 ], [Mo 6 O 16 (OMe) 2 {MeC(CH 2 O) 3 } 2 {Mn(CO) 3 } 2 ] 2− and [Mo 8 O 20 (OMe) 4 {MeC(CH 2 O) 3 } 2 ] 2− . Although the frameworks of the majority of derivatives are based on tetranuclear units which display the common rhomb‐like structure, the alternative cubane‐type arrangement is observed in [Mo 2 O 5 (OMe) 5 {M(CO) 3 } 2 ] − .
