资源简介：
The divalent lanthanide borohydrides [Ln(BH4)2(THF)2] (Ln = Eu, Yb) have been prepared in a straightforward approach. The europium compound shows blue luminescence in the solid state, having a quantum yield of 75%. Nonradiative deactivation of C–H and B–H oscillator groups could be excluded in the perdeuterated complex [Eu(BD4)2(d8-THF)2], which showed a quantum yield of 93%. The monocationic species [Ln(BH4)(THF)5][BPh4] and the bis(phosphinimino)methanides [{(Me3SiNPPh2)2CH}Ln(BH4)(THF)2] have been prepared from [Ln(BH4)2(THF)2]. They show significantly lower or no luminescence. Using the diamagnetic compound [{(Me3SiNPPh2)2CH}Yb(BH4)(THF)2], we performed a 2D 31P/171Yb HMQC experiment.
