摘要：

The pallada(IV)cyclopentane complex [Pd(OH)(C4H8){(pz)(3)BH}] crystallizes with m-cresol to form [Pd(OH)(C4H8){(pz)(3)BH}.2(3-MeC(6)H(4)OH)], in which the hydroxopalladium(IV) group is hydrogen-bonded to two m-cresol groups and to the more acidic pentafluorophenol to form [Pd(OH2)(C4H8){(pz)(3)BH}.(C6F5O)](2), in which the aquapalladium(IV) group is strongly hydrogen-bonded to two C6F5O- ions in a centrosymmetric dimer. These first structural studies in diorganopalladium(IV) chemistry include the first examples of hydroxo- and aqua-palladium(IV) complexes, and also provide models for possible pallada(IV)cyclic intermediates in organic synthesis involving palladium complexes as catalysts.
