[(C 5 Me 5 ) 2 Sm] 2 (μ-η 2 :η 2 -PhC 4 Ph) is formed from the reaction of [(C 5 Me 5 ) 2 Sm(μ-H)] 2 with PhC≡CH, from the thermolysis of (C 5 Me 5 ) 2 Sm(C≡CPh)(THF) at 80-145°C, from the reaction… Continue Reading
The effects of cyclopentadienyl ring size on the geometry of bimetallic organosamarium complexes have been studied by comparing the X-ray crystal structure of [(C5H4Me)2(THF)Sm(μ-Cl)]2, prepared from… Continue Reading
(C5Me5)2Sm(thf)2(thf = tetrahydrofuran) reacts with PhCCCCPh to form [(C5Me5)2Sm]2C4Ph2 which is found by X-ray crystallography to have η2-co-ordination of Sm3+ to the carbon–carbon multiple bonds.
SmI2(THF)2 reacts with two equivalents of K[1,3-(Me3Si)2C5H3] to form [(Me3Si)2C5H3]2Sm(THF) (1). 1 can be desolvated by sublimation at 80°C and 4 × 10−6 Torr to give [(Me3Si)2C5H3]2Sm (2). 1… Continue Reading
