Network topology approach to new allotropes of the group 14 elements

Journal article, 2013

The network topology approach has been a major driving force in the search for new metal-organic frameworks and coordination networks. In this work we demonstrate how this method not only generated the recently described "T12" allotrope of the group 14 elements, identical to the cdp topology found in the structure of CdP2, but also a number of other candidate structures for polymorphs of these network-forming elements. Data on such network structures have been compiled since the 1950's and is readily accessible through several internet based systems. The usefulness of topology for the classification of these allotropes is emphasised.
