Bis(2-chloro-1,4-dimethylbenzene) chromium (O), bis(4-chloro-1,2-dimethylbenzene)chromium(O), bis- (2,4-dichloro-1-methylbenzene)chromium(O), bis- (2,6-dichloro-1-methylbenzene)chromium(O) and bis- (1,4-dichlorobenzene)chromium(O) were prepared by co-condensation of vaporized chromium with the corresponding organic ligand at 77 K. The compositions and sandwich structures of the complexes were confirmed through mass spectra, the major fragmentation patterns of which are discussed, and the IR spectra. On the basis of symmetry considerations and IR absorption spectra, a cis-structure is suggested for the first and last mentioned compounds and a trans-structure for the others. The UV absorption spectra were also recorded.
