Abstract
The title compound, (1,2-di-eta (5) -cyclopentadienyl-1,2-dimethyltrans-1,2 -diphenylethane)(1,2-dimethoxyethane)calcium, trans-Ph-2(CH3)(2)C-2(eta (5) -C5H4)(2) Ca(DME) or [Ca(C26H24)-(C4H10O2)], was synthesized by reductively coupling 6,6-methylphenylfulvene with activated calcium in the presence of dimethoxyethane (DME). The trans isomer was isolated by fractional crystal lization. The Ca atom is four-coordinate and is eta (5)-bonded to both cycl opentadienyl rings [Ca-Cp(centroid) distance = 2.381 (3) Angstrom] and the O atoms of the coordinated solvent chelate ligand [Ca-O = 2.350 (2) and 2.4 04 (2) Angstrom].
