Dicaesium pentacyanotricuprate(I), Cs₂Cu₃(CN)₅

A. M. Chippindale, S. J. Hibble, A. H. Pohl and E. J. Bilbé

Abstract: Cs₂Cu₃(CN)₅ has a layered structure consisting of [Cu₃(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 CN 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 CN group is terminal and ordered with C bonded to Cu.
