Abstract: The title complex, [Pd{(py)₃COH}₂](NO₃)₂, where (py)₃COH is tris(pyridin-2-yl)methanol (C₁₆H₁₃N₃O), studied at 150 and 298 K, has the potentially tridentate ligands present as bidentate ligands, with the Pd atom at a centre of symmetry. At 150 K, the Pd-N distances are 2.022 (3) and 2.026 (3) Å. The mean planes of the coordinated pyridine groups form dihedral angles of 42.1 (1) and 45.3 (1)° (at 150 K) with the coordination plane; the uncoordinated rings situated either side of the coordination plane form dihedral angles of 42.2 (1)° with it. The nitrate ions are regular and interact weakly with the hydroxyl group.

Formula: [Pd(C₁₆H₁₃N₃O)₂](NO₃)₂
