A new series of palladium complexes derived from DPMNPH ligand was reported. The
compounds under study were characterized by elemental analyses, spectroscopic studies
and single crystal X-ray measurement in case of DPMNPH ligand. The crystal structure
of DPMNPH ligand showed that ligand crystallized as orthorhombic with space group
P212121. Furthermore, H1 atom is intramolecularly bonded to the pyridinic N4 with N1-
H1=0.92(3) Å, H1…N4=1.87(2)Å, N1….N4=2.615(2) Å and N1-H1…N4=137(2)°. Both
the complexes were found to be excellent catalyst in Heck reaction in the presence of
base.
