(Nitrato-κO)(2,2′:6′,2′′-terpyridine-κ(3) N,N′,N′′)palladium(II) nitrate

The title complex, [Pd(NO(3))(C(15)H(11)N(3))]NO(3), comprises a cationic Pd(II) complex and a nitrate anion. In the complex, the Pd(II) cation is four-coordinated in a distorted square-planar coordination geometry defined by the three N atoms of the tridentate 2,2′:6′,2′′-terpyridine ligand and one O atom from the NO(3) (−) anion. In the crystal, the complex mol­ecules are stacked in columns along the a axis being connected by π–π stacking [closest inter-centroid separation between pyridyl rings = 3.878 (3) Å]. The connections between columns and anions to sustain a three-dimensional architecture are C—H⋯O hydrogen bonds. [Image: see text]
