Q. Li and T. C. W. Mak

Synopsis: New inclusion compounds are described: (C₂H₅)₄NCl.2[(NH₂)₂CSe] has a layer-type selenourea-chloride host structure, isomorphous (n-C₃H₇)₄NX.3[(NH₂)₂CSe] (X = Cl, Br) feature an open-channel network constructed from wide seleno-urea-halide ribbons and (n-C₃H₇)₄NI.3[(NH₂)₂CSe] is characterized by a composite ribbon composed of a zigzag arrangement of selenourea molecules with iodide ions attached to both sides.
