Abstract
The asymmetric unit of the title compound, [Co(NO3)2L]n,L=N-(pyridine-2-ylmethyl)pyridine-3-amine (C11H11N3), contains one CoIIcentre, two nitrate anions and oneLligand in which the Cpy—C—N—Cpymoiety adopts atransconformation with a torsion angle of −173.1 (3) Å. The coordination geometry of the CoIIatom is a distorted pentagonal bipyramid. One amine N atom from theLligand and four O atoms from two η2-nitrato ligands form the basal plane and two pyridyl N atoms from two symmetry-relatedLligands occupy the apical positions [N—Co—N = 171.86 (11)°]. The displacement of the central CoIIatom from the basal plane (r.m.s. deviation = 0.085 Å) is 0.1491 (12) Å. Each bidentate nitrate group is bonded asymmetrically to the cobalt atom in an chelating fashion. The CoIIions are linked by theLligands to form a zigzag chain propagating along thec-axis direction. Within the zigzag chain, C—H...O hydrogen bonds between the ligands and the nitrate anions are observed. Adjacent zigzag chains are connectedviaintermolecular π–π stacking interactions [centroid-to-centroid distance = 3.844 (2) Å] between the pyridine rings together with N/C—H...O hydrogen bonds.
