The reaction of (C{sub 5}Me{sub 5})Zr(CH{sub 3}){sub 3} with ((C{sub 5}H{sub 4}Me){sub 2}Fe)(BPh{sub 4}) in THF yields ((C{sub 5}Me{sub 5})Zr(CH{sub 3}){sub 2}(THF){sub 2})(BPh{sub 4}) (1) via oxidative cleavage of a Zr-CH{sub 3} bond. X-ray diffraction reveals that the cation of 1 adopts a square-pyramidal/four-legged piano-stool structure with cis CH{sub 3} groups. The orientations of the THF ligands and the Zr-O bond distances suggest that Zr-O {pi}-bonding is important for at least one of the THF ligands. Data for 1: a = 14.551 (2) {angstrom}, b = 15.191 (4) {angstrom}, c = 17.852 (19) {angstrom}, {beta} = 92.26 (3){degree}, V = 3,943 (6) {angstrom}{sup 3}, Z = 4 in space group P2{sub 1}/c. Reaction of 1 with excess dmpe in THF solution yields ((C{sub 5}Me{sub 5})Zr(CH{sub 3}){sub 2}(dmpe)(THF))(BPh{sub 4}) (2), which also has been characterized by X-ray diffraction.
