Two isolated structural motifs in one crystal: One of which fills helical channels in another

An unusual compound Zn1.5(Hsdpa)(bpy)1.5(H2O)4 (1) comprising two isolated coordination polymers has been obtained by hydrothermal reactions, in which helical channels of a 3D host framework A [Zn(Hsdpa)(bpy)(H2O)2]− are filled with the guest infinite 1D polymer chains B [Zn0.5(bpy)0.5(H2O)2]+.
