Abstract
The cyclopalladated complexes Pd{2-CH{2}C{6}H{4}P(o-tol){2}}{(pz){n}BH{4}{-}{n}} and Pd(C{6}H{4}C{5}H{4}N-C}2{, N'){(pz){n}BH{4}{-}{n}} [n=2, 3; pz=pyrazol-1-yl] have been synthesised from the corresponding halide bridged cyclometallated dimers; the crystal structures of the complexes for which n=3 have been determined. The complexes Pd{2-CH{2}C{6}H{4}P(o-tol){2}}{(pz){n}BH{4}{-}{n}} (n=2, 3) and [Pd{2-CH{2}C{6}H{4}P(o-tol){2}}(@m-O{2}CMe)]{2} are unreactive towards oxidation by alkyl halides, iodobenzene and 4-bromoanisole.
