Bismuth acetate complexes, preparation

Tl -bismolyl derivative [Mn(CO)jL] (81) (L=2,5-Me2C4H2Bi). Two papers describe the formation of triiron complexes [ Fe(CO)4 3(p -BiR)] in which bismuth is tetrahedral, addition of acetic acid to which affords rectangular complexes [Fc(CO)4(p-BiR)]2 . Another publication details the preparation of a whole range of complexes in which a bismuth nitrate unit is linked to two metal centres , while thermolysis of NaBi03 and [Mo(CO)J in methanol for a day, followed by addition of Et4NBr yields the unusual cluster [Mo3(CO)9(p -Bi) p -(OMej)Mo(CX))3 ][NEt4]2, which contains a naked bismuth atom (82) . ...
