N2 - We herein describe a tricyclic phosphine with previously unreported tris(homoadamantane) cage architecture. That water-soluble, air- arid-thermally stable ligand, 1,4,7-triaza-9-phosphatricylo[5.3.2.1(4,9)]tridecane (hereinafter referred to as CAP) exhibits unusual chemical behavior toward gold and gold compounds: it readily reduces Au(III) to Au(0), promotes,oxidative dissolution of nanocrystalline gold(0) with the formation of water-soluble trigonal CAP-Au(I) complexes, and displaces cyanide from [Au(CN)(2)](-) affording triangular [Au(CAP)(3)](+) cation. From the stereochemical point of view, CAP can be regarded as an intermediate between 1,3,5-triaza-7-phosphaadamantane (PTA) and very unstable aminophosphine synthesized :by Verkade's, group: hexahydro-2a,4a,6a-triaza-6b-phosphacyclopenta[cd]pentalene: The chemical properties of CAP are likely related to its anomalous Stereoelectronic profile: combination, of strong electron-donating power (Tolman's electronic parameter 2056.8 cm(-1)) with the low steric d
