In Situ Formed Guanidinium Cations as Templates To Direct Fabrication of Honeycomb-like CuCN Networks.

The solvothermal reaction of CuSCN and 1,2-bis(diphenylphosphino)ethane (dppe) in mixed solvents acetonitrile/ n-hexane/(methanol or ethanol) gave a honeycomb-like guanidinium cyanocuprate [C(NH 2) 3)]·[Cu 2(CN) 3]. The in situ formed cations C(NH 2) 3+act as templates to direct the formation of the CuCN network in which multiple weak N−H····N/C hydrogen interactions potentially exist between the cations C(NH 2) 3+and the {CuCN} 6rings.
