Three-coordinated tilings of the plane by pentagons, heptagons and hexagons are presented and used for the construction of tubular, toroidal and helical carbon structures. Physically realistic 3D geometries are formed from the corresponding adjacency matrices. The electronic structures are determined with the help of a simple tight-binding method.
