Structures of Complex Compounds from Five- and Six-Membered Hetarenes 

Complexes of Five-Membered Heterocycles with One Heteroatom 

Reviews quoted earlier as well as (96MI20) contain a large number of examples that indicate the prevailing J7-(tj5-) complex formation 80 and 81 for five-membered hetarenes. A recent example is the product of the reac- 

Coordination Compounds of Hetarenes with Group V Elements 

The a- (171-) complexes are known for pyrroles and phospholes. For pyrroles, both N-metal derivatives (10) and organometallic compounds (82) and (83) are described. A similar situation is observed in pyrrolylimido complexes Pwu-[MX(NNC4H4)(dppe)2]+ and cis,mer-[WX2(NNC4H4) (PMe2Ph)3], whose reaction ability has been studied comprehensively (95JA12181). A mixed 771 175 coordination is realized in the binuclear Cr(CO)5 complex of azaferrocene (90MI4).
