摘要：

The tetranuclear cluster [NBu4](2)[(C6F5)(6)(mu-OH)(3)Pt3HgCl] is obtained by reacting the mononuclear platinum complex [NBu4](2)[Pt(C6F5)(3)Cl] 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, P2(1)/n with a = 11.9770(10), b = 26.092(3), c = 24.991(2) Angstrom, beta = 92.900(10)degrees, D-calc = 2.009 Mg m(-3) for Z = 4 and R = 0.076 utilizing 13 657 data with F-o(2) greater than or equal to 2 sigma(F-o(2)). The UV-vis spectrum of the solid sample has been studied revealing that the compound is strongly luminescent. (C) 2000 Elsevier Science S.A. All rights reserved.
