The reaction between two equivalents of (Me3Si)2CH}(Ph)PH(BH3) (1) and Bu2Mg, followed by two equivalents of BH3·SMe2, gives the corresponding phosphido-bis(borane) complex, which may be crystallised as two distinct chemical species: the complex [(Me3Si)2CH}(Ph)P(BH3)2]2Mg(THF)4·THF (2a), and two different THF solvates (1 : 1 and 1 : 2) of the solvent-separated ion triples [(Me3Si)2CH}(Ph)P(BH3)2]2[Mg(THF)6]·THF
