The monometallic complex with Rh(COD) of 5-hydro and 7-hydro-s-indacenide h
as been synthesized and structurally characterized. It crystallizes in the
triclinic space group P1 with a = 12.513(2), b = 15.902(2), c = 8.423(1) An
gstrom, alpha = 97.0(1), beta = 91.4(1), gamma = 111.7(1)degrees. The geome
try of the ligand was revealed to be substantially different from that of i
ts 2,6-dimethylated homologues. An explanation for this behaviour is given
in terms of electronic and mesomeric effects. (C) 2000 Elsevier Science S.A
