The Structure of [PdCl₂{(Py)₂(PyH)CH-N′,N″}][PdCl₄]_0.5.2H₂O (Py = Pyridin-2-yl), a Complex With Protonated 2,2′,2″-Methylidynetrispyridine as a Bidentate Ligand

Abstract

Crystals of dichloro[2,2′,2″-methylidynetris(pyridin)-1-ium-N′,N″]palladium(II) hemi[tetra-chloropalladate(II)] dihydrate are monoclinic, P2₁/c, a 8.558(5), b 15.516(7), c 16.153(5) a, P 112.07(4)°, Z 4. The cations [PdCl₂{(Py)₂(PyH)CH-N′,N″}]⁺ have square-planar geometry for palladium, with the ligand in a boat conformation and having an uncoordinated protonated pyridine group.
