The crystallization of two solvates of Au11(PPh3)7(SCN)3, 2Au11(PPh3)7(SCN)3·2C6H6·0.5EtOH (1) and Au11(PPh3)7(SCN)3·3EtOH (2), with (1) containing two independent molecules of the cluster, allows the positions of all of the ligands to finally be identified. Despite the bent nature of the thiocyanate ligands, they occupy similar sites to the ones that contain halogen ligands in Au11(PPh3)7Cl3, Au11(PPh3)7I3, and related molecules. However, the relative orientations of these thiocyanate ligands differ in the three cluster sites. |
