摘要：
The reaction of [Au9(PPh3)8](NO3)3 with 3 equiv of NBu4[Au(C6F5)2] affords the neutral cluster [Au10(C6F5)4(PPh3)5] in high yield. X-ray diffraction reveals that the cluster has a toroidal geometry based on a ring of edge- and face-sharing tetrahedra that share a common central vertex. It crystallizes in space group P2(1)/c with a = 18.339 (4) angstrom, b = 15.603 (4) angstrom, c = 41.510 (12) angstrom, beta = 95.10 (2)-degrees, and Z = 4. This cluster represents the second example of both an Au10 and an organometallic gold cluster.
