Abstract
Two novel dimeric palladium(II) complexes with flexible pyridyl dithioether bridging ligands, [Pd(L1)Cl2]2 (1) and [Pd(L2)Cl2] (2), where L1=1,3-bis(2-pyridylthio)propane and L2=1,3-bis(4-pyridylthio)propane, have been synthesized and structurally characterized by X-ray diffraction analyses. In both complexes, each PdII center is four-coordinated in the trans-form by two chloride anions and two nitrogen donors from two distinct ligands. Complex 1 exhibits a unique 20-membered metallomacrocyclic structure with twisted conformation, while 2 shows a dinuclear 28-membered metallomacrocycle with planar conformation. In addition, there are weak C-H ⃛Cl or C-H ⃛S hydrogen bonding interactions in both complexes, resulting in different 3-D supramolecular architectures.
