==Structure and properties== While the electronic and solid-state-supported structure of the chloride congener is not known (due to low solubility in common analytical solvents), several studies have been carried out on the bromo and iodo derivatives. The complexes display a temperature-dependent interconversion between square-planar and tetrahedral geometries (diamagnetic and paramagnetic) in polar organic solvents (Keq between 1-3.68, depending on the solvent and temperature). In contrast, dichloro(1,2-bis(diphenylphosphino)ethane)nickel adopts a static square-planar (diamagnetic) structure in solution.
