摘要：

The reaction of the dianion [Pt(3)RU(6)(CO)(21)(mu-H)(2)](2-), generated in situ by the deprotonation of [Pt(3)RU(6)(CO)(21)(mu-H)(3)(mu(3)-H)], 1, With [Cp*Ir(NCMe)(3)](2+) and HgI2, has yielded two new higher nuclearity cluster complexes Pt(3)RU(6)(CO)(21)(mu(3)-IrCp*)(mu(3)-H)(2), 5, and [NBu(4)]-[Pt(3)RU(6)(CO)(21)(mu(3)-HgI)(mu(3)-H)(2)], 6, in the yields 15% and 35%, respectively. Both compounds were characterized by single-crystal X-ray diffraction analysis. They both contain layer segregated triangular Pt-3 and Ru-3 groupings stacked one upon the other with the Pt-3 group in the center. The heterometal atom occupies a triply bridging position across one of the Ru2Pt triangles. The hydride ligands have adopted triply bridging positions on the two Ru-3 triangles.
