“…[6] Our test case, [{Zn 2 (cam) 2 (dabco)} n ] (+)-1 for (+)cam and (À)-1 for (À)cam) with an anisotropic tetragonal crystal system is such a layer-based MOF containing the binuclear "paddle wheel" zinc carboxylate unit {Zn 2 (COO) 4 N 2 } with distorted octahedral geometry, in which chiral camphorate bridge the dimeric zinc units into infinite planar layers {Zn 2 cam 2 } n . Linear N-donor ligands dabco occupy the axial Zn sites, perpendicularly to these {Zn 2 cam 2 } n layers, leading to a scaffold-like 3D structure.…”
