Synthesis and characterization of carbamoyl methyl pyrazole(CMPz) compounds of palladium(II) chloride: The crystal and molecular structure of [PdCl2{C3H3N2CH2CONiBu2}2]

Carbamoyl methyl pyrazole compound of palladium(II) chloride of the type [PdCl2L2] (where L = C5H7N2CH2CON(C4H9)2, C5H7N2CH2CON(iC4H9)2, C3H3N2CH2CON(C4H9)2, or C3H3N2CH2CON(iC4H9)2) has been synthesized and characterized by IR and 1H NMR spectroscopy. The structure of the compound [PdCl2{C3H3N2CH2CONiBu2}2] has been determined by single crystal X-ray diffraction and shows that the ligands are bonded through the soft pyrazolyl nitrogen atom to the palladium(II) chloride in a trans disposition.
