Well-defined hydrocarbon soluble strontium fluoride and chloride complexes of composition [LSr(thf)(mu-F)(2)Sr(thf)(2)L] and [LSr(thf)(mu-Cl)(2)Sr(thf)(2)L]

Reaction of LSrN(SiMe3)(2)(thf) 1 (L = CH(CMe-2,6-i-Pr2C6H3N)(2)) with Me3SnF and LAlCl(Me), respectively, gave the first example of a strontium mono fluoride complex [LSr(thf)(mu-F)(2)Sr(thf)(2)L](2) and the corresponding chloride derivative [LSr(thf)(mu-Cl)(2)Sr(thf)(2)L] 3.
