Once again, this is not very common for first row transition metal ions. Examples with three different geometries have been identified:
Trigonal planar Geometry: Well known for main group species like CO32- etc., this geometry has the four atoms in a plane with the bond angles between the ligands at 120 degrees.
Figure 1: The Trigonal planar [Cu(CN)3]2- system
Trigonal pyramid Geometry: More common with main group ions.
T-shaped: The first example of a rare T-shaped molecule was found in 1977.
