Crystal Structure Determination of Zeolite Nu‐6(2) and Its Layered Precursor Nu‐6(1)

A small-pore pentasil zeolite (Nu-6(2)), which has a new topology, is obtained by thermal treatment of the 4,4′-bipyridyl silicate Nu-6(1). Crystal structure solution of the new zeolite and its layered precursor was achieved by combining high resolution X-ray powder pattern, direct methods, and model building. Nu-6(2) is characterized by a 1D channel system of two independent sets of eight-membered rings (see picture).
