The reaction of K\n 12<\/jats:sub>\n Sn\n 17<\/jats:sub>\n with gold(I) phosphine chloride yielded K\n 7<\/jats:sub>\n [(\u03b7\n 2<\/jats:sup>\n \u2010Sn\n 4<\/jats:sub>\n )Au(\u03b7\n 2<\/jats:sup>\n \u2010Sn\n 4<\/jats:sub>\n )](NH\n 3<\/jats:sub>\n )\n 16<\/jats:sub>\n (\n 1<\/jats:bold>\n ) and K\n 17<\/jats:sub>\n [(\u03b7\n 2<\/jats:sup>\n \u2010Sn\n 4<\/jats:sub>\n )Au(\u03b7\n 2<\/jats:sup>\n \u2010Sn\n 4<\/jats:sub>\n )]\n 2<\/jats:sub>\n (NH\n 2<\/jats:sub>\n )\n 3<\/jats:sub>\n (NH\n 3<\/jats:sub>\n )\n 52<\/jats:sub>\n (\n 2<\/jats:bold>\n ), which both contain the anion [(Sn\n 4<\/jats:sub>\n )Au(Sn\n 4<\/jats:sub>\n )]\n 7\u2212<\/jats:sup>\n (\n 1\u2009a<\/jats:bold>\n ) that consists of two [Sn\n 4<\/jats:sub>\n ]\n 4\u2212<\/jats:sup>\n tetrahedra linked through a central gold atom.

A similar reaction with [2.2.2]crypt as a sequestering agent led to the formation of crystals of [K[2.2.2]crypt][MesCuMes] (\n 5<\/jats:bold>\n ).
