Uninodal 4-connected 3D nets. III. Nets with three or four 4-rings at a vertex
M. O’Keeffe · Acta Crystallographica Section A Foundations of Crystallography · 1995
A description is given of 4-connected nets with one kind of vertex in which at least three of the shortest rings containing each pair of edges are 4-rings. 21 such nets are identified and characterized topologically. Some correspond to well known zeolite structures, but most are believed to be new.
