(Pyridine-2,6-di-carboxyl-ato-κ3O,N,O′)(2,2′:6′,2′′- terpyridine-κ3N,N′,N′′)nickel(II) di-methyl-formamide monosolvate monohydrate

摘要

In the title complex, [Ni(C 7 H 3 NO 4 )(C 15 H 11 N 3 )]·C 3 H 7 NO·H 2 O, the Ni II ion is six-coordinated within an octa-hedral geometry defined by three N atoms of the 2,2′:6′,2′′-terpyridine ligand, and two O atoms and the N atom of the pyridine-2,6-di-carboxyl-ate di-anion. In the crystal, the complex mol-ecules are stacked in columns parallel to the a axis being connected by π – π stacking [closest inter-centroid separation between pyridyl rings = 3.669?(3)??]. The connections between columns and solvent mol-ecules to sustain a three-dimensional architecture are of the type water-O—H?O(carbon-yl) and pyridyl-, methyl-C—H?O(carbon-yl).
