✦ Synopsis

Polycyclic compounds / Centropolyindans / Chromium arene complexes / Stereochemistry The reaction of 9H,10H-4b,9a([1,2]benzenomethano)indeno[l,2alindene (triptindan, TRIP) with Cr(CO)6 in Bu,O/THF (9:l) affords a monocomplex (A) together with two bis-Cr(C0)3 complexes (B and C ) and one tris-Cr(C0)3 complex (D). The relative yields of the four complexes as well as their tendency to lose Cr(C0)3 are related to stabilizing intramolecular factors. All the Cr(C0)3 units of the complexes A, B, and D are
