Abstract
A tetra-dentate ligand, namely, ortho-xylylenebis(pyridyl-triazole), o-xpt, was synthesized using the 'click' method and complexed with Pd(BF(4))(2). In the title com-plex, bis-{μ-1,1'-(o-xylylene)bis-[4-(pyridin-2-yl)triazole]-κN (3):N (3')}dipalladi-um(II) tetra-kis-(tetrafluoridoborate)-di-methyl-formamide-diethyl ether (1/2/1), as the BF(4) salt, and including di-methyl-formamide and diethyl ether solvent mol-ecules, with stoichiometry [Pd(2)(C(22)H(18)N(8))(2)](BF(4))(4)·2C(3)H(7)NO·C(4)H(10)O, the Pd complex and the disordered diethyl ether mol-ecule lie on inversion centers. The ligand coordinates to the Pd(II) centers with square-planar geometry, forming a dimeric macrocycle. The Pd⋯Pd separation in the complex [Pd(2)(o-xpt)(2)](4+) cation is 3.6184 (4) Å. In the crystal, the complex mol-ecules are stacked along the b axis, with π-π inter-actions between the pyridyl-triazole ligands of two mol-ecules.
