solid state by infrared and Mossbauerspectroscopic techniques. The structures of the antimony trihalide complexes appear to be based on halogen bridged polymers in which the stereochemical activity of the lone pair of electrons varies with the halogen, the highest p-character of the lone pair being observed with the trifluoride adduct. Mossbauer results for the PhSbI 2 complexes suggest a ψ-octahedral

Transition metal complexes with doubly bridging antimony(I) halide ligands, [eta6-arene(CO)2Cr}2 SbX] (1-4) have been synthesized by photochemically induced reductive dehalogenation of SbX3 (X = Cl, Br, 1). The electronic and steric features of the complexes 1-4 were modified by varying the coordinated arene (arene = C6H6, mesitylene, hexamethylbenzene, C6H5CF3). 1-4 are more sensitive than analogous complexes with isoelectronic complex fragments eta5-CpR(CO)2Mn}, their instability increasing with increasing number of + I-substituents at the arene. Two X-ray crystal structure investigations confirmed the expected trigonal planar coordination of Sb(I)). The complexes [arene(CO)2Cr}2SbX] proved to be less acidic at the Sb centre than other complexes of the type [L(n)M}2SbX] (L(n)M = (CO)5Cr, CpR(CO)2Mn) revealing a high pi-backbonding capacity of the complex fragments arene(CO)2Cr}.
