Abstract

Two Hg(II) complexes with the cluster-complex ligand [Re ₆(μ₃-Se)₈(PEt₃) ₅(PTA)](SbF₆)₂ (PTA = 1,3,5-triaza-7- phosphaadamantane), {[Re₆(μ₃-Se)₈(PEt ₃)₅(PTA)(Hg₃I₇)](SbF ₆)}_n·(CH₃CN)_n (1) and {[Re₆(μ₃-Se)₈(PEt₃) ₅(PTA)]₂(Hg₄I₉)}(SbF ₆)₃·2CH₃CN (2), were prepared and structurally characterized. The two compounds were obtained from reactions conducted at different temperatures under otherwise identical conditions. Recrystallization of the room-temperature product 2 in a different solvent mixture produced yet another new Hg(II) complex, {[Re₆(μ ₃-Se)₈(PEt₃)₅(PTA)](Hg ₃I₈)}·CH₃CN (3) which may be considered as a consequence of the dissociation of the kinetic product 2 in solution and the re-assembly of necessary components to generate the new compound upon crystallization. The solid-state structure of 1 contains polymeric cluster columns, in which the PTA ligand adopts a hitherto unknown coordination mode with simultaneous coordination of all four (one P and three N atoms) potentially coordinating atoms.
