✦ Synopsis
To date, no conformational search of inorganic complexes has been reported that searches for all the conformations and configurations available to the complex. This is due to the various coordination geometries that transition metal ions can adopt and the difficulties in conducting conformational searches with systems that have connected ring systems, such as the ones formed when a Äw Ž . x 3q metal ion binds a multidentate ligand. Using three test complexes Co dien , 2 w Ž .Ž .x 3q w Ž .
