An approach is proposed for encoding the gold-ammonia bonding patterns on the conformational manifold of the [image omitted]-(NH3)m, Z = 0, ±1, clusters in order to implement simple unary and binary logic gate operations. The gold-ammonia bonding patterns are governed by two different basic ingredients: the anchoring Au-N bond and the nonconventional N-H···Au hydrogen bond, and exhibit distinct characteristics as the charge of the cluster varies within Z = 0, ±1. The conformers of the small cluster, AuZ-(NH3)2, and of the nanometric size one, [image omitted], are chosen as illustrative examples. The dependence of the bonding patterns on the overall charge state of the cluster allows to implement the logic gates NOT, FAN-OUT, AND, NAND, OR, NOR, INH, XOR, and XNOR and to identify the outputs using an IR readout protocol.
