This article describes the simplest members of an infinite family of knots and links that have achiral piecewise-linear embeddings in which linear segments (sticks) meet at corners. The structures described are all corner- and stick-2-transitive –

Crystallographic descriptions of isogonal piecewise linear embeddings of 1-periodic weaves and links (chains) are presented. These are composed of straight segments (sticks) that meet at corners (2-valent vertices). Descriptions are also given of som

Graphitic carbon nitrides (g-CNxHy) are an important class of materials for driving energy conversion processes such as photocatalysis and fuel cell reactions. However, a poor understanding of stru...

We describe five new zeolitic framework types, fav, faw, fax, fay, and sod-t, that are structurally related to faujasite. They are derived from isomorphic expansions of the tetrahedral nets associa...

Piecewise linear descriptions are presented of weavings of threads, loops and 2-periodic nets. Crystallographic data are provided for regular structures, defined as those with one kind (symmetry-related) of vertex (corner) and edge (stick). These inc

The creation of knotted, woven and linked molecular structures is an exciting and growing field in synthetic chemistry. Presented here is a description of an extended family of structures related to the classical `Borromean rings', in which no two ri

This work considers non-crystallographic periodic nets obtained from multiple identical copies of an underlying crystallographic net by adding or flipping edges so that the result is connected. Such a structure is called a `ladder' net here because t

We present a small set hypothetical zeolite frameworks that are structurally related to faujasite. They are found by examination of the -t nets of the Frank-Kasper phases, which optimize the conditions for regular-tetrahedral nets. The new frameworks

We describe mathematical knots and links as piecewise linear – straight, non-intersecting sticks meeting at corners. Isogonal structures have all corners related by symmetry ("vertex" transitive). Corner- and stick-transitive structures are termed
