N2 - Abstraction of chloride from the Pd complex {[η3-2,6-(tBu2PCH2) 2C6H3)]PdCl with AgBF4 in THF gives {[η3-2,6-(tBu2PCH2) 2C6H3)]Pd(THF)}+BF4 -. Attemped crystallization of this THF complex produced the aqua complex {[η3-2,6-(tBu2PCH2) 2C6H3)]Pd(OH2)}+BF 4-. Crystal structures of two crystalline forms of this compound are reported. In {[η3-2,6-(tBu2PCH2) 2C6H3)]Pd(OH2)}+BF 4-·THF, one hydrogen of the water is hydrogen bonded to the oxygen of the THF, and the other hydrogen is hydrogen bonded to an F of the BF4- anion. Another crystalline form has no THF, but has both of the hydrogens of water hydrogen bonded to different BF4- anions, such that two different BF4- anions bridge two {[η3-2,6-(tBu2PCH2) 2C6H3)]Pd(OH2)}+ cations. A crystal structure is also reported for the palladium chloride complex [η3-2,6-(tBu2PCH2) 2C6H3)]PdCl.
