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)
摘要:
Reaction of potassium diphenylphosphide with elemental selenium is shown to give [K(Se2PPh2)(THF)(2)](2) 1, which further reacts with InCl3 to yield [In(Se2PPh2)(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.
