Synthesis and Crystal Structure of Binuclear Silver(I) Complex with 2-nitro-(2-pyridylsulfanylmethyl)benzene

1 INTRODUCTION Metallosupramolecular species with metal-metal interactions have been designed and synthesized due to their potential applications as functional materi- als[1]. For Ag(I) coordination compounds, short Ag(I) –Ag(I) separations have been found in many bi- and polynuclear complexes[2~4], and these short metal- metal distances have been attributed to the ligand ar- chitecture[5, 6]. Thus, the rational design of bi- and polynuclear Ag(I) complexes must recognize the in- here…

Synthesis and Crystal Structure of Binuclear Silver(I) Complex with 2-nitro-(2-pyridylsulfanylmethyl)benzene

The reaction of 2-nitro-(2-pyridylsulfanylmethyl)benzene L with silver nitrate produces a centrosymmetric binuclear complex bis(2-nitro-(2-pyridylsulfanylmethyl)benzene-N,S)- bis(nitrato-O,O)-disilver(I), [AgLNO3]2 1. The crystal is of triclinic, space group P1, with a = 7.383 (3), b = 8.340(3), c = 12.003(4) ?, α = 95.069(6), β = 93.498(5), γ = 102.734(6)o, C24H20Ag2N6- O10S2, Mr = 832.32, V = 715.6(4) ?3, Z = 1, Dc = 1.931 g/cm3, F(000) = 412, μ = 1.581 mm?1, R= 0.0351 and wR = 0.0749 Each silver atom is tetrahedrally coordinated by two O atoms from bidentate nitrate, one S atom from a ligand and one N atom from another ligand. Furthermore, Ag– Ag interactions have been observed in the complex.
