A. Singhal et al., SYNTHESIS AND CHARACTERIZATION OF CHLORO PYRAZOLATO BRIDGED BINUCLEARORGANOPLATINUM(II) COMPLEXES - SINGLE-CRYSTAL STRUCTURE OF [PT2PH2(MU-CL)(MU-PZ)(PME2PH)2], Journal of organometallic chemistry, 479(1-2), 1994, pp. 87-91
Chloro/pyrazolato-bridged binuclear organoplatinum(II) complexes of th
e type [Pt2Ar2(mu-Cl)(mu-NN)(PR3)2] (Ar = Ph or C6H4OMe-4; NNH = pyraz
ole (pzH), 3,5-dimethylpyrazole (dmpzH) or 3,4,5-tri-methylpyrazole (t
mpzH); PR3 = PBu3, PMe2Ph or PMePh2) have been synthesized. These comp
lexes exist exclusively in the cis form in which the phosphine ligands
are trans to the bridging pyrazolate group. The crystal structure of
[Pt2Ph2(mu-Cl)(mu-pz)(PMe2Ph)2] is reported.
