  Disparate properties of gold(I) converge to produce the first   known cube assembly of eight Au(I) atoms connected by four   N-bridging amidinate ligands on the sides of the cube, capped   above and below by hyper-coordinate carbon atoms from a   phosphorous ylide.  There are no phosphines coordinated to   the Au(I) atoms.  The cluster is formulated as   [Au8{CH(NC8H9)2}4{(.eta.5-C)P(C6H5)2(CH3)}2].  It displays a   strong green luminescence under UV light.  The novel product   was generated in an attempt to produce luminescent species of   gold(I) with mixed C- and N-coordination, an arrangement not   abundant in the literature.  The formation and structure of   this cluster is reported.
