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 C[triple-bond]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[triple-bond]N group is terminal and ordered with C bonded to Cu.
