Résumé
The tetranuclear cluster [NBu4]2[(C6F5)6(μ-OH)3Pt3HgCl] is obtained by reacting the mononuclear platinum complex [NBu4]2[Pt(C6F5)3Cl] with Hg(NO3)2 followed by appropriate work-up. The X-ray study reveals that the compound possesses three donor-acceptor Pt→Hg bonds unsupported by any covalent bridges. The crystallographic parameters are: monoclinic, P21/n with a=11.9770(10), b=26.092(3), c=24.991(2) Å, β=92.900(10)°, Dcalc=2.009 Mg m<sup>-3</sup> for Z=4 and R=0.076 utilizing 13 657 data with Fo<sup>2</sup>≥2σ(Fo<sup>2</sup>). The UV-vis spectrum of the solid sample has been studied revealing that the compound is strongly luminescent. © 2000 Elsevier Science S.A.
