Molecular and polymeric Hg(II) complexes with a PTA (1,3,5-triaza-7-phosphaadamantane) complex of the [Re6(μ3-Se)8]2+ core-containing cluster as ligand

The synthesis and structural studies of three novel Hg(II) complexes, molecular and polymeric, produced with the use of a PTA (1,3,5-triaza-7-phosphaadamantane) complex of the [Re6(μ3-Se)8]2+ core-containing cluster as ligand, are reported. The distinctly different compounds were isolated from otherwise identical reaction mixtures at different reaction temperatures. The salient coordination modes of the cluster-bound PTA ligand, including one for which there is no literature precedent, are discussed, together with some discussion of the profound temperature effects observed on the identity of the products.
