The {last|final} decade has witnessed {significant|substantial|considerable|important} advances {in the|within the|inside the} synthesis and structure determination of atomically precise metal nanoclusters. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, {little|small|tiny} is {known|recognized|identified} {about the|concerning the|regarding the|in regards to the} condensed matter properties {of these|of those} nanosized metal nanoclusters packed {in a|inside a|within a} crystal lattice {under|below|beneath} {high|higher} {pressure|stress}. {Here|Right here} {using|utilizing|making use of|employing|working with|applying} density function theory calculations, we simulate the crystal of a representative superatomic gold cluster, [Au25(SR)18]0 (R = C2H5), {under|below|beneath} {various|numerous|different|a variety of|several|many} pressures. At ambient {conditions|circumstances|situations}, [Au25(SC2H5)18]0 clusters are packed {in a|inside a|within a} crystal {via|by way of|through|by means of} dispersion interactions; {being|becoming|getting} a 7e superatom, {each|every|each and every|every single} cluster carries a magnetic moment of 1μB or {one|1|a single|one particular} unpaired electron. Upon {increasing|growing|escalating|rising} compression (from {10|ten} to 110 GPa), we observe the formation of inter-cluster Au-Au, Au-S, and S-S covalent bonds {between|in between|among|amongst|involving} staple motifs, thereby linking the clusters into a network.
