Abstract

The Nickel (II) ion forms many stable complexes as predicted by the Irving Williams series. This experiment is about preparation and stereochemistry of nickel phosphine complexes. The nickel phosphine complexes, which were prepared are NiBr2(PPh3)2 and NiBr2(PCy3)2. The first part of the experiment is to prepare the nickel complexes. After preparing nickel phosphine complexes NiBr2 (PPh3)2 and NiBr2 (PCy3)2, the complexes have been analyzed for structural determination. The complexes were analyzed by the Magnetic Moments of solids-The Johnson Matthey Balance, UV-visible (electronic spectra), Infrared spectra (normal range) and Far-infrared spectra (which were supplied in the practical booklet).
