_topol_net.overall_topology_TOPOS

Name:
_topol_net.overall_topology_TOPOS

Definition:

   
    The overall topology symbol according to the TOPOS nomenclature. TOPOS
    symbols NDn are interpreted as follows: N is a sequence of degrees
    (coordination numbers) of all independent nodes; D is one of the letters
    C (chain), L (layer) or T (three-periodic) designating the dimensionality
    of the net; and n enumerates non-isomorphic nets with a given ND sequence.
    For finite (molecular) graphs the symbols NMK-n are used, where k is the
    number of vertices (atoms) in the graph.

Example:

3,3,4T3 The third non-isomorphic three-periodic trinodal net with two 3-coordinated and one 4-coordinated independent nodes.
