Coordination complexes were known - although not understood in any sense - since the beginning of chemistry, e.g. The crystal structure consists of the packing of discrete monomeric molecules, the closest Re-Re distance being approximately 9.5 A. Density functional theory (DFT) calculations were performed to address the question of the preference for a specific coordination geometry in the related Mn II complexes [Mn (acac) 2 (bpy)] (trigonal prismatic) and [Mn (acac) 2 (phen)] (distorted octahedral). A trigonal prism is a good choice for a coordination geometry that leads to a high negative value of D and possible SMM behavior in d 7 ions: trigonal prismatic cobalt(II) complexes have been recently found to demonstrate slow relaxation in a small or even zero external static dc fields, with the largest barrier obtained being 76 cm –1. Say you put a ligand in the trigonal complex (or an equatorial ligand in a trigonal bipyramidal complex) on the x -axis, where z is the "axial" axis.
