Coordination chemistry of diselenophosphinate complexes: the X-ray single-crystal structures of [K(Se2PPh2)(THF)2]2 and [In(Se2PPh2)3].L (L = THF, PhMe).
Reaction of potassium diphenylphosphide with elemental selenium is shown to give [K(Se(2)PPh(2))(THF)(2)](2) 1, which further reacts with InCl(3) to yield [In(Se(2)PPh(2))(3)] 2. Crystallization of 2 from either THF or PhMe gave 2.THF or 2.PhMe, respectively, both of which form loosely linked dimers in the solid state via Se...Se intermolecular van der Waals interactions. Decomposition of 2 has been studied by TGA.
