Dimensionality of coordination polymers decided by the type of hybridization of the central carbon atom of the solvent molecule that coordinates to an alkali metal cation: From discrete to 3D networks based on a gold(iii) bis(dithiolene) complex

Abstract

The solvent coordination with sodium metal ions leads to the formation of coordination polymers from discrete to 3D networks based on a gold bis(dithiolene) complex {[AuIII(btdt)2]-} (btdt = 2,1,3-benzenethiadiazole-5,6-dithilolate); all these complexes show great discrepancy in dimensionality of the self assembled coordinated networks due to the effect of solvents, which we have explained in terms of the difference in geometry of the hybridized orbitals of the central carbon attached to the coordinating atom (N or O in the present study). © 2010 The Royal Society of Chemistry.
