As a discovery of C\_C coupling and amine elimination reaction by treatment of \{6\|dimethylamino\|6\|methylfulvene\} with zirconium tetrachloride, experiments using amino\|substituted benzofulvene 1a or aminopentafulvene 2a, instead of 6\|dimethylamino\|6\|methylfulvene, gave \{bis\{\[1\|(dimethylamino)\}\}ethenyl\|indenyl\]zirconium dichloride 1c which was characterized by X\|ray diffraction as monoclinic, space group \%C2/c\%, \%a\%=2.028 8(4) nm, \%b\%=0.981 7(2) nm, \%c\%=1.458 9(3) nm, \%β\%=115.73(3)°, \%V\%=2.617 5(9) nm\+3, \%Z\%=4, \%R\%=0.072 3, and bis\[(1\|methyl\|4,5\|dihydro\|2\|pyrrolnyl)cyclopentadienyl\]zirconium dichloride 2c as triclinic, space group \%P\%1, \%a\%=0.807 49(16) nm, \%b\%=\{0.943 40(19)\} nm, \%c\%=\{1.423 8(3)\} nm, \%α\%=91.04(3), \%β\%=97.41(3), \%γ\%=106.68(3)°, \%V\%=1.028 6(4) nm\+3, \%Z\%=2, \%R\%=0.080 0.
