Dendrimer-like cyanoruthenate anions with high potential connectivity derived from a [Ru(bpym)3]2+ core

Structural and photophysical properties of luminescent cyanometallates [M(diimine)(CN)4]2− and their supramolecular assemblies

“…32) in which all three external sites are occupied by {Ru(CN) 4 } 2fragments, generating an array of twelve externally-directed cyanide groups in a D 3 symmetric array (in contrast to D 3h for [{Ru(CN) 4 } 3 (m-HAT)] 6-, described in the previous section). 34 An interesting possibility associated with this is its chirality: resolution of the starting material [Ru(bpym) 3 ] 2+ will allow preparation of enantiopure [Ru{(m-bpym)Ru(CN) 4 } 3 ] 4complexes to be prepared. These will be intriguing possibilities for crystal engineering applications given their combination of high connectivity and chirality which immediately suggest opto-electronic behaviour such as circularlypolarised luminescence and second harmonic generation arising in the networks.…”
