Abstract

Cocondensation of C₅H₄(SiMe₃)₂, hexane, and metal vapour at -196°C yields M{C₅H ₃-1,3-(SiMe₃)₂}₂ [M = Ca (1), Sr (2), and Ba (3)] which reversibly bind tetrahydrofuran (thf); X-ray structure determinations on the adducts [M{η-C₅H₃-1,3-(SiMe ₃)₂}₂(thf)], [M = Ca (4) Sr, (5)] show they are monomeric bent metallocenes, M-C, M-O 2.662(10)-2.718(9), 2.310(9), (4), 2.78(4)-2.84(5), 2.49(3) Å, (5); Centroid-M-Centroid, 139.1, (4), 134°, (5).
