We present a tight-binding molecular-dynamics investigation on the structural, elastic and electronic properties of the smallest periodic tetrahedral carbon schwarzites fcc-, fcc- and fcc-. Although their unit cells are equivalent to the fullerenes , and , respectively, their stability is found to be much higher. Moreover they present alternatively metallic or insulating character, which would make this class of hypothetical materials suitable to a wide range of applications.
