The arrangement of small molecules—known as ligands—around transition metal atoms affects how the metal atoms behave. This is important because transition metals are used as catalysts in the synthesis ...

Metal dimer complexes with d 8 square planar metallic centers provide a ... distance and the optical and reactive properties of the molecule. Understanding and predicting the equilibrium spatial ...

Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar ...

The resulting complex had what is known as square-planar geometry. This means that the nickel is in the center and the ligands are arranged around it at the four compass points, all in the same plane.
