Solid-state structures metallic crystals

Over the last few years, we have made a number of novel discoveries using reactive salt fluxes in the crystal growth experiment of mixed-metal oxides. The most important outcome that these salt-inclusion solids have demonstrated is the propensity for structure- directing effects of the employed salt. These hybrid solids have revealed fascinating solid-state structures ranging from nanoclusters to three-dimensional open frameworks of current interest. Solids featuring mag-... 

Finally, a metal- -T 6-arene interaction that generates a supramolecular onedimensional array has been reported in the solid-state structure of the (2,6-diphe-nylpyridine)gold(III) derivative [Au(CN) 2,6-NC5H3(C6H4)2-C,C, N [ [66]. Its crystal structure shows that the planes of the planar molecules are parallel, but slip-stacked via intermolecular Au- -T 6-arene contacts in which the distance between the gold atom and the centroid of the arene is 3.428 A. A representation of this structure is shown in Figure 5.35. 

The structures of 204-207 have been established in the solid state by single crystal X-ray diffraction. Clusters 205 and 206 are based on the Ru6C octahedral skeleton. The [2.2]paracyclophane ligand in 205 coordinates over a triangular metal face, and in 206 one [2.2]paracyclophane adopts a similar face-capping bonding mode and the other coordinates in a terminal mode to an apical Ru atom. The metal polyhedron in 204 is relatively open in comparison to the octahedron having only nine Ru-Ru bonds. A carbide atom occupies the central cavity and interacts with five of the six Ru atoms.
