Hg(TePh)(2) (Ph-phenyl) reacts with CdI(2)(PPh(3))(2), PPhMe(2) (Me-methyl), and PPh(3)/Zn(NO(3))(2)center dot 4H(2)O to give the compounds [Hg(4)(TePh)(7)IPy](n) (Py=pyridine) (1), [Hg(8)Te(TePh)(14)(PPhMe(2))(2)]center dot 0.5DMF (DMF=dimethylformamide) (2) and [Hg(11)(TePh)(18)Te(2)Py(3)](n) (3).While 1 and 3 assemble polymeric clusters, 2 can be described as a super tetrahedron with a Te(2-) ion located in the center. The geometric topology of cluster 3, together with some experimental evidences, suggests that its core is attained by the spontaneous fusion of clusters 1 and 2. (C) 2010 Elsevier B.V.
