✦ Synopsis

Reaction of equimolar amounts of the metalloarsaalkene [(η 5 -[Fe(CO) 4 ] (3), and [Cr(CO) 5 ] (4). These feature η 1 coordination of the arsaalkene ligand via the arsenic atom. The mo-C 5 Me 5 )(CO) 2 FeAs=C(NMe 2 ) 2 ] (1) with the carbonyl complexes [Ni(CO) 4 ], [Fe 2 (CO) 9 ], and [{(Z)-cyclooctene}Cr(CO) 5 ], lecular structures of the complexes 3 and 4 have been determined by X-ray diffraction analyses. respectively, affords the adducts [(η 5 -C 5 Me 5 )(CO) 2 FeAs-{M(CO) n }=C(NMe 2 ) 2 ] with [M(CO) n ] = [Ni(CO) 3 ] (2);
