Description
The title compound crystallizes in the orthorhombic space group P212121 with Z=4 and lattice parameters a=1744.2(4), b=1360.7(4), c=751.3(5) pm. An X-ray analysis shows the compound to consist of discrete (h5-C5H5)2-Ti(Cl)NCMe+ cations and FeCl4- anions. The cation has a distorted tetrahedral structure Ti-C: 231.9-237.6 pm; Ti-Z: 203 and 204 pm; Ti-Cl: 230.4 pm; Ti-N: 213.5 pm; Z-Ti-Z: 133.20; Cl-Ti-N: 91.70 (Z: centre of cyclopentadienyl ring). The relatively short Ti-Cl bond length indicates a modest Ti-Cl π-bonding contribution. The tetrachloroferrate(III) anion possesses a nearly undistorted tetrahedral geometry (Fe-Cl: 216.0-218.5 pm; Cl-Fe-Cl: 109.0-111.10). Moessbauer and X-ray photoelectron spectroscopic data confirm the crystallographically derived structural features. (orig.)
