    The self‐assembly of nanostructures is dominated by a limited number of strong coordination elements. Herein, we show that metal–acetylene π‐coordination of a tripodal ligand (L) with acetylene spacers gave an M3L2 double‐propeller motif (M=CuI or AgI), which dimerized into an M6L4 interlocked cage (M=CuI). Higher (M3L2)n oligomers were also selectively obtained: an M12L8 truncated tetrahedron (M=CuI) and an M18L12 truncated trigonal prism (M=AgI), both of which contain the same double‐propeller motif. The higher oligomers exhibit multiply entangled facial structures that are classified as a trefoil knot and a Solomon link. The inner cavities of the structures encapsulate counteranions, revealing a potential new strategy towards the synthesis of functional hollow structures that is powered by molecular entanglements. Die Komplexierung eines verdrehten Triarylmethan‐Liganden mit CuI‐ oder AgI‐Ionen ergibt M6L4‐, M12L8‐ und M18L12‐Koordinationspolyeder, die als vernetzte und verknäuelte Oligomere eines hypothetischen M3L2‐Doppelpropellers betrachtet werden können, die durch schwache Acetylen‐π‐Wechselwirkungen stabilisiert werden.
