PREPARATION AND X-RAY CRYSTAL AND MOLECULAR-STRUCTURE OF CIS-[(DPPP)PD(H2O)(OSO2CF3)](-) AND CIS-[(DPPP)PD(H2O)(2)](2+)(OSO2CF3)(2)(-) - COORDINATED WATER TRIFLATE HYDROGEN-BONDS()(OSO2CF3)()

Reaction of 1 and 2 equiv of water, respectively, with s-(1,3-bis(diph enylphosphino)propane)palladium(II) triflate yields the corresponding monoaquo and diaquo cationic Pd complexes 2 and 3 in 86% and 99% yield respectively, as yellow, air-stable, microcrystalline solids. The mol ecular structures of [(dppp)Pd(OH2)(OSO2CF3)(2)], (2) and [(dppp)Pd(OH 2)(2)(OSO(2)CF3)(2)], (3) have been determined by single-crystal X-ray crystallography. Complex 2 crystallizes in the monoclinic space group P2(1)/n with Z = 4, a = 13.857(5) Angstrom, b = 13.335(5) Angstrom, c = 19.054(8) Angstrom, beta = 102.98(2)degrees, R = 0.0461, and R(w) = 0.0614 at 298 K. Complex 3 crystallizes in the triclinic space group P ($) over bar 1 with Z = 2, a = 11.440(1) Angstrom, b = 11.800(1) Ang strom, c = 14.269(1) Angstrom, a = 95.66(1)degrees, beta = 94.49(1)deg rees, gamma = 109.15(1)degrees, R = 0.0301, and R(w) = 0.0467 at 298 K .
