✦ Synopsis

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 (nBu 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 ] 2À and [Mo 4 O 10 (OMe) 6 ] 2À , [Mo 2 O 4 {MeC(CH 2 O) 3 } 2 {Mn(CO) 3 }] À and [Mo 3 O 6

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 ] À .
