Micro-Columnar Crystals with (-O=V-Pd-)_n Infinite Chain Structures Assembled by Hetero-Dinuclear Metal Complexes

Abstract:

The inorganic and organic hybrid compound, [O=VPd(2-Pyd-)4]n (2-Pyd- = 2-pyridonate) (1), was synthesized by assembling its monomer units in the organic solution. X-ray absorption spectroscopic (XAFS) studies indicated that oxidation states of the vanadium and palladium ions in 1 were +IV and +II, and the distance between them was estimated to be 2.698-2.700 Å. Scanning electron microscope (SEM) observation revealed that the compound 1 shapes in long columnar crystals with micrometer-sized cross section. EXAFS and IR studies suggested that the O=V oxygen atom interacted to the central palladium ion in the neighboring monomer unit, forming the inorganic infinite chain structure, -(O=V-Pd)n-, in the columnar crystals of 1.
