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. Reference: Aman, F., Asiri, A. M., Siddiqui, W. A., Arshad, M.
