Abstract/Summary

Cs2Cu3(CN)(5) has a layered structure consisting of [Cu-3(CN)(5)](2-) sheets stacked in an ABAB fashion along the c axis, with Cs+ cations lying between the sheets. The sheets are generated by linking -(CuCN) - chains, in which the C N groups are ordered, via [Cu(CN)(3)](2-) units. The two bridging cyanide groups of each [Cu(CN)(3)](2-) unit show partial 'head-to-tail' disorder of C and N, whilst the third C N group is terminal and ordered with C bonded to Cu.
