  摘要：

  Reaction of [HgCl2(PPh3)(2)] with one equivalent of thiosalicylic acid (tsaIH(2), HSC6H4CO2H) and excess triethylamine, followed by recrystallisation from dichloromethane-diethyl ether gives the compound [Hg-2(tsal)(2)(PPh3)(2)] (2). This has a bis(S,O)-chelated mercury centre with a nido-trigonal bipyramidal coodination, with the four oxygens of the two carboxylates also coordinated to a Hg(PPh3)(2) moiety. When a reduced quantity of pyridine was used as the base a different crystalline product was isolated. This was characterised as [Hg-2(tsal)(2)(PPh3)(2)][Hg(tsalH)(2)] (3), which contains the same [Hg-2(tsal)(2)(PPh3)(2)] moiety found for 2, co-crystallised with a [Hg(tsalH)(2)]. The two mercury-thiosalicylate species are connected by means of O-H...O hydrogen bonding. (C) 2004 Elsevier B.V. All rights reserved.
