Abstract

Two Hg(II) complexes with the cluster-complex ligand [Re 63-Se)8(PEt3) 5(PTA)](SbF6)2 (PTA = 1,3,5-triaza-7- phosphaadamantane), {[Re63-Se)8(PEt 3)5(PTA)(Hg3I7)](SbF 6)}n·(CH3CN)n (1) and {[Re63-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, {[Re63-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.
