The cocrystallization of [Cu(SCN)]n chains and [Cu2(4,4‘-bpy)(CN)2]n (4,4‘-bpy = 4,4‘-bipyridine) layers generated a 3-D pseudopolyrotaxane compound, [Cu2(4,4‘-bpy)(CN)2]·[Cu(SCN)] (1), which can also be viewed as a 3-D network constructed by linkages of 2-D sheets and 1-D chains via unsupported CuI−CuI interactions. The CuI−CuI contact of 2.651(4) Å in 1 is the shortest unsupported CuI−CuI distance documented to date, indicating cuprophilic attractions.
