The title compound, [Cu3(C6H18NSi2)(C9H24N3Si2)2], is a trinuclear CuI complex. A crystallographic twofold axis passes through one CuI atom and the N atom of the bis(trimethylsilyl)amide ligand that bridges between the other two CuI atoms. The Cu-Cu bonds bridged by the guanadinate ligands [2.7913 (9) Å] are slightly longer than the Cu-Cu bond bridged by the bis(trimethylsilyl)amide ligand [2.6405 (11) Å].
