Mono-, bis-, and tris(tricarbonylchromium) complexes of triptycene wer
e synthesized by the reaction of triptycene with Cr(CO)(6). The stereo
chemistry of the true isomeric bimetallic complexes of C-s and C-2v sy
mmetries was determined from the NMR spectra. X-ray structures of the
bimetallic (C-s) and trimetallic complexes are presented.
