Article abstract of DOI:10.1016/0022-328X(87)80232-2

Six pyrazoles have been cyclopalladated by reaction with either lithium tetrachloropalladate or palladium acetate and the dimeric products converted to monomeric acetylacetonate complexes.The crystal structure of acetylacetonato<2-(3-methyl-5-phenylpyrazol-1-yl)phenyl-C¹,N^2'>palladium(II) has been determined.Crystals are monoclinic: a 15.035(3), b 8.541(1), c 16.340(4) Angstroem, β 117.10(1) deg, P2₁/c, Z = 4; the structure was refined to R = 0.030.
