Polycatenated Bilayer Structure Containing Honeycomb-like 6 3 Layers

A new luminescent Zn(II) compound, [Zn 2 (IN) 3 (bpy) 0.5 (CH 3 COO)]·2(DMA) ( 1 , IN = isonicotinate, bpy = 4,4′-bipyridine, DMA = N,N-dimethylacetamide), was synthesized under solvothermal condition and structurally characterized by single crystal X-ray diffraction. Compound 1 features a (3,4)-connected bilayer structure with honeycomb-like 6 3 layers and bpy pillars. Each individual bilayer is catenated with two adjacent bilayers, giving rise to a rare 2D + 2D → 3D polycatenation motif.
