[WS4Cu3I2]- and [WS4Cu4]2+ secondary building units formed a metal-organic framework: large tubes in a highly interpenetrated system.
A 3D metal-organic framework, {[WS(4)Cu(4)(dpbp)(4)](2+)·[WS(4)Cu(3)(dpbp)(2)I(2)](-)·I(-)}(n)·xSolvent, [dpbp = 4,4'-di(4-pyridyl)biphenyl] with an unprecedent 8-fold non-equivalent interpenetration mode is presented, which contains four anionic and four cationic frameworks formed by tetranuclear [WS(4)Cu(3)I(2)](-) and pentanuclear [WS(4)Cu(4)](2+) SBUs with long dpbp ligands. Large rhombus-shaped tubes with diagonal dimensions of ~20 × 10 Å are formed in spite of high interpenetration.
