Pr) in benzene, thf or diethyl ether, volatile compounds of formulae [M(OR') 3 (NH 3 ) x ] (X = 0-3), M(OR') 3 (thf) 3 and M(OR') 3 (Et 2 O) x ( x = 0.33 or 0.5) have been isolated. X-ray crystal structures were determined for [SC 2 OCH(CF 3 ) 2 } 6 (NH 3 ) 4 ], [Pr 2 OCMe (CF 3 ) 2 } 6 (NH 3 ) 4 ], [YOCMe(CF 3 ) 2 } 3 (thf) 3 ], [LaOCMe(CF 3 ) 2 } 3 (thf) 3 ] and [Pr 3 OCMe 2 (CF 3 ) 2 } 9 ].
