Bis[μ-2-(3-pyridylmethyl)-2H-benzotriazole]bis[nitratosilver(I)]

Abstract

In the title centrosymmetric binuclear AgI complex, [Ag2(NO3)2(C12H10N4)2], each AgI center is coordinated by one pyridine and one benzotriazole N-donor atom of two inversion-related 2-(3-pyridylmeth­yl)-2H-benzotriazole (L) ligands, and an O atom of a coordinated NO3 − anion in a distorted T-shaped geometry. This forms a unique box-like cyclic dimer with an intra­molecular non-bonding Ag⋯Ag separation of 6.327 (2) Å. Weak inter­molecular Ag⋯O(nitrate) inter­actions [2.728 (4) and 2.646 (3) Å] link the binuclear units, forming a two-dimensional network parallel to (100). Inter­molecular C—H⋯O hydrogen-bonding inter­actions, involving the L ligands and the coordinated NO3 − anions, link the sheets, forming a three-dimensional framework.

“…Bis-heterocyclic chelating or bridging ligands have been used extensively to construct functional coordination complexes that contain different hetero-aromatic ring systems, see: ; Constable & Steel (1989); Steel (2005). For related structures, see: Hu et al (2008); Huang et al (2008); Liu et al (2006Liu et al ( , 2007; Liu, Sun et al (2008); ; Richardson & Steel (2003). For the synthesis of ligand L, see: Liu, Sun et al (2008).…”

“…In our previous work, to further investigate the influences of the N-donor spatial position of pendant pyridyl group in structurally related benzotriazol-1-yl-based pyridyl ligands on the structures of their coordination complexes, two new N-containing heterocyclic ligands 1-(4-pyridylmethyl)-1H-benzotriazole (4-pbt) and 2-(3-pyridylmethyl)-2H-benzotriazole (3-pbt) were designed and prepared. Their reaction with AgNO 3 offered an one-dimensional double helical coordination polymer (Hu et al 2008;Liu, Sun et al 2008). To further investigate the influence of different counter-anions on the self-assembly process of coordination complexes, we chose to use L to construct new functional Ag I complexes through its reaction with AgClO 4 .…”
