ABSTRACT
The asymmetric unit of the title compound, {[Ag(C11H11N3)]NO3·2(CH3)2SO} n , comprises one Ag(I) atom, one N-(pyridine-4-ylmeth-yl)pyridine-3-amine ligand, one nitrate anion and two dimethyl sulfoxide mol-ecules. The Ag(I) atoms are bridged by two pyridine N atoms from two symmetry-related ligands, forming a helical chain and adopting a slightly distorted linear coordination geometry [N-Ag-N = 175.37 (8)°]. The helical chain, with a pitch length of 16.7871 (8) Å, propagates along the b-axis direction. In the crystal, symmetry-related right- and left-handed helical chains are alternately arranged via Ag⋯Ag inter-actions [3.4145 (4) Å] and π-π stacking inter-actions [centroid-centroid distance = 3.650 (2) Å], resulting in the formation of a two-dimensional supra-molecular network extending parallel to (100). Weak Ag⋯O [2.775 (2), 3.169 (4) and 2.690 (2) Å] inter-actions, as well as several N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, contribute to the stabilization of the crystal structure. Parts of the dimethyl sulfoxide solvent molecule are disordered over two sets of sites in a 0.937 (3):0.063 (3) ratio.

Mentions: The mol­ecular components of the title structure are shown in Fig. 1 ▶. The asymmetric unit consists of one AgI atom, one N-(pyridin-4-ylmeth­yl)pyridine-3-amine ligand, one nitrate anion and two DMSO mol­ecules. The S atom of one of the DMSO mol­ecules is disordered over two sites [site-occupancy factors of 0.937 (3) for S2 and 0.063 (3) for S2′]. The Ag atom links two pyridine N atoms from two symmetry-related ligands, forming a helical chain. Thus the AgI atom is two-coordinate in a slightly distorted linear coordination geometry [N—Ag—N = 175.37 (8)°], with the Ag—N bond lengths of 2.158 (2) and 2.162 (2) Å. The helical chain propagates along the b-axis direction (Fig. 2 ▶) and its pitch length is 16.7871 (8) Å, much longer than that [10.135 (2) Å] of the monohydrated AgI coordination polymer reported by Zhang et al. (2013 ▶). The two pyridine rings coordinating to the Ag atom are tilted by 9.77 (16)° with respect to each other. In the N-(pyridin-4-ylmeth­yl)pyridine-3-amine ligand, the two pyridine rings are almost perpendicular, the dihedral angle between their mean planes being 86.28 (7)°.
